Ṛtudharma: A Sanātana Dharma Perspective on Menstruation
Introduction
Modern discourse frequently approaches menstruation through the frameworks of biology, medicine, or social reform. While these perspectives are important for advancing female reproductive health, they tend to treat menstruation as an isolated physiological event. The Indian Knowledge System, however, adopts a fundamentally different approach. Bhāratīya thought situates menstruation within a comprehensive framework of cosmology, medicine, ritual, ecology, and philosophy. This perspective does not separate the body from nature, instead, it creates a relation between the human body and cyclical orders that govern the universe.
Menstruation, known as ṛtudharma or rajodharma, is interpreted not merely as a reproductive function but as an expression of ṛtu (seasonal order) and ṛta (cosmic order) that regulates creation, preservation, and renewal. In the Bhāratīya framework, the female body is not viewed as separate from prakṛti but as participating in the same cyclical order that governs the seasons, the movement of celestial bodies, the agricultural fertility, and the continuous renewal of life.
Unlike common tropes that treat menstruation as an isolated biological event, inviting social scorn, the classic Sanātana Dharma perspective observes menstruation through the lens of cosmic order that governs the universe.
Purpose and Scope
This article examines ṛtudharma through the Indian Knowledge System, exploring its connections with Āyurveda, Jyotiṣa, Dharmaśāstra, and Śākta traditions. It highlights the relationship between menstruation, bodily health, cosmic rhythms, ritual observances, and sacred ecology, while considering the contemporary relevance of these perspectives.
One of the defining characteristics of Bhāratīya civilisation is its understanding of time as cyclical rather than linear. The succession of seasons, lunar phases, agricultural traditions, and biological processes all form a pattern governed by ṛta and ṛtu. Thus, ṛtudharma is also explained within this larger cosmological framework.
The Saṃskṛta term ‘ārtava’ is employed by āyurveda to denote menstruation and female reproduction principles [2]. The term rajodharma is etymologically rooted in the word raja, implying menstrual blood. All these terms that are used for women’s reproductive physiology are similar to those words used to describe the rhythms of nature’s creative power. Hence, the terminology for menstruation and female reproduction in the Indian Knowledge System is rooted in understanding and equating rhythms of the human body with those of the physical and cosmic planes.
Āyurveda examines menstruation as an essential indicator of reproductive health and bodily equilibrium. Jyotiṣa correlates reproductive rhythms with celestial cycles. Dharmaśāstra texts prescribe observances that recognize menstruation as a liminal stage requiring physical rest and temporary ritual withdrawal. Śākta tradition elevates the menstrual cycles to the levels of sacred symbolism by identifying it with the creative power of the feminine divine. Although these disciplines differ in their methodology, they converge to recognise menstruation as an integral component of life’s cyclical order.
The Indian Knowledge System approaches menstruation through a broader intellectual framework that integrates biological functions, cosmological cycles, and cultural values. This perspective does not separate the body from nature, instead, it creates a relation between the human body and cyclical orders that govern the universe.
Menstrual cycle is also known as rajodharma, where the root word ‘raja’ relates to menstrual blood. The Saṃskṛta term ‘ārtava’ is employed by āyurveda to describe menstruation and female reproductive physiology [2]. However, menstruation is most commonly known as ṛtudharma, whose root word expresses ṛtu or seasonal/cyclic changes and ṛta or the cosmic order [1]. This relationship echoes the Bhāratīya philosophy of how biological rhythms mirror the cosmic rhythms and human well-being is related to harmony with natural cycles.
The menstrual cycle is not viewed as an isolated function but as part of the same cyclical order that governs the seasons, the lunar phases, agricultural rhythms, and procreation. Just as nature undergoes a period of renewal through changing seasons, the female body that represents prakṛti also experiences cyclical processes that prepare it for the possibility of creation and regeneration. Texts on āyurveda, jyotiṣa, and kāmaśāstra frequently associate menstruation with the lunar cycle, emphasising that the human body exists in harmony with the universe [1]. Thus, menstruation is regarded as a natural process of renewal that is responsible for creation of life in the universe.
The following verse by Varāhamihira discusses female physiology in Bṛhajjātaka, relating menstruation to the influence of the Moon and Mars.
कुजेन्दु तु प्रतिमासमार्तवं गते तु षोडर्क्षमनुष्णदीधितौ ।
अतोऽन्यथास्थे शुभपुंग्रहेक्षिते नरेण संय्योगमुपैति कामिनी ।। १ ।। [3]
(Bṛhajjātakam, Caturtho'dhyāyaḥ – 4.1)
kujendu tu pratimāsamārtavaṃ gate tu ṣoḍarkṣamanuṣṇadīdhitau |
ato’nyathāsthe śubhapuṃgrahekṣite nareṇa saṃyyogamupaiti kāminī || 1||
(Bṛhajjātakam, Caturtho'dhyāyaḥ – 4.1)
प्रतिमास मंगल और चंद्रमा के कारण स्त्रियों को ऋतुधर्म होता है। यदि स्त्री की जन्मराशि से अनुपचय स्थान में चंद्रमा हो और मंगल से दृष्ट हो, तो गर्भधारण योग्य ऋतु होता है। और इससे भिन्न में चन्द्रमा हो तथा शुभ पुरुष ग्रह (गुरु) से दृष्ट हो तो स्त्री को पुरुष का संयोग होता है। [3]
The monthly menstruation is caused by Mars and the Moon, when the Moon is situated in a house of suffering. But situated otherwise in aspect from a benefic, male planet, then a woman is overtaken by man in intercourse. [4]
The verse illustrates the epistemological foundations of jyotiṣa that seeks correspondences between brahmāṇḍa or macrocosm and piṇḍa or microcosm. In the Bhāratīya thought, human physiology is understood in harmony with the cosmic rhythms, rather than being independent of them. Hence, rajodharma or ṛtudharma is a manifestation of the universe's cyclicity that connects the body to the celestial order.
The observances associated with menstruation in Bhāratīya society are among the most discussed and are often the most misunderstood aspect of its culture. Dharmaśāstra texts describe menstruation as a period of aśauca, during which women refrain from ritual worship and certain domestic responsibilities. Modern interpretations frequently reduce the meaning of aśauca to impurity, whereas the word actually points to a period of austerity, rest, and self-purification [1].
In Bhāratīya tradition, aśauca as a social practice commonly accompanies several important transitions in life, including childbirth and death of close relatives. These observances recognise the biological, psychological, and social need for space during temporary transformations. Such transformations alter one’s ritual status and thereby necessitate a prescribed rite of purification. Hence, the purification rituals associated with aśauca are connected to ritual preparedness rather than an act of ‘otherisation’ or moral judgement.
Traditional texts also recommend that women avoid strenuous labour and sexual intercourse during menstruation. These prescriptions acknowledge the physical demands associated with the menstrual cycle and create a space for rest and recovery. In many households, women were temporarily relieved of routine domestic work, allowing the body to complete its natural processes without unnecessary exertion. Although the customs related to menstruation differed across Bhārata, the intention behind the restrictions was to allow the body’s natural rhythms to stabilise while maintaining ritual discipline.
Āyurveda’s Aṣṭāṅgahṛdaya understands menstruation as a normal physiological function essential for reproduction.
मासि मासि रजः स्त्रीणां रसजं स्त्रवति त्र्यहम्।
वत्सराद्वादशादूर्ध्वं याति पञ्चाशतः क्षयम् ॥८॥ [7]
(Aṣṭāṅgahṛdaya, Śārīrasthānam – 1.7)
māsi māsi rajaḥ strīṇāṃ rasajaṃ stravati tryaham
vatsarādvādaśādūrdhvaṃ yāti pañcāśataḥ kṣayam ||7||
(Aṣṭāṅgahṛdaya, Śārīrasthānam – 1.7)
स्त्री द्वादश वर्ष की अवस्था से लेकर पचास वर्ष की अवस्था तक प्रतिमास तीन दिनाें तक रसजनित रजन (रक्त) का स्राव करती है, यह प्रतिमास जो योनि-द्वारा रक्त का स्राव होता है इसको स्त्रियों का मासिक रज कहा जाता है। यह मासिक रज बारह वर्ष से आरम्भ हो कर प्रतिमास तीन दिन स्राव होता है। पचास वर्षकी अवस्था पूर्ण होने पर स्वयं स्राव होना बन्द हो जाता है। यह सामान्य मर्यादा है, कहीं देश भेद से इस काल प्रमाण में न्यूनाधिकता भी हो जाती है । [7]
From the age of twelve until the age of fifty, women undergo a monthly three-day period of menstruation where raja or menstrual blood flows through their yoni (female genitalia). This state begins near the age of twelve and ends near the age of fifty, such is the natural rhythm of the female body. The period of the menstrual cycle can change with a change in state of the woman herself.
The verse demonstrates the clinical precision with which āyurveda observes the rhythms of the female reproductive cycle. Other dharmaśāstra texts state the importance of rājasika or prāna śakti known as apāna vāyu during the menstrual phase. They specify that during rajasrāva or flow of menstrual blood, apāna vāyu requires an unobstructive flow in the downward direction to ensure the movement removes excessive bodily energies. Thus, excessive physical exertion and emotional stress were believed to disturb the balance of menstrual cycles. Hence, the period of aśauca were prescribed with menstruation to ensure reduced physical labours, increased self-care with hygiene as a central focus, and abstinence from ritual observances.
Bhāratīya civilisational belief system recognises biological transition of the female body through carefully structured rites of passage. Menarche, the onset of the menstrual cycle, is marked by important social and cultural rituals, traditions defining the beginning of womanhood for a female through ceremonies that affirm feminine identity and prepares young girls for adulthood.
The onset of the menstrual cycle, known as menarche, is marked by celebrations in many regions of Bhārata. Ṛtudharma or menstruation is a major life transition for a young girl. Another term for menstruation in the Indian Knowledge System is rajodharma, rooted in the word ‘raja’ which implies menstrual blood. Therefore, via such nomenclature, menstrual cycles were considered a part of the natural rhythm of the body that works in symphony with prakṛti. This natural biological change in a young girl’s body and its related social responsibilities are marked through ceremonies and rituals.
अष्टवर्षा भवेद्गौरी नववर्षा तु रोहिणी ।।
दशवर्षा भवेत्कन्या अत ऊर्ध्वं रजस्वला ॥ ६ ॥ [5]
(Parāśarasmṛtiḥ, Saptamo'dhyāyaḥ – 7.6)
aṣṭavarṣā bhavedgaurī navavarṣā tu rohiṇī |
daśavarṣā bhavetkanyā ata ūrdhvaṃ rajasvalā ||
(Parāśarasmṛtiḥ, Saptamo'dhyāyaḥ – 7.6)
आठ वर्ष की लड़की 'गौरी', नौ वर्ष की 'रोहिणी', और दस वर्ष की 'कन्या' कहलाती है। इसके बाद 'रजस्वला' कहलाती है। [5]
A girl of eight years of age is called Gaurī, in her ninth year she is called Rohinī, a girl of ten (years in age) is denominated as Kanyā; and thenceforward she is called Rajasvalā. [6]
The aforementioned verse shows that girls were assigned the name of rajasvalā once they were close to the age of menarche. The term and the ceremonies related to menarche depict the traditional importance and celebration assigned to the achievement of womanhood in a female’s life.
The verse recognises rajasvalā as a distinct stage in a woman's life rather than a mere biological event. Menarche represents the transition from childhood to reproductive maturity and therefore, acquires ritual, educational, and social significance. Across various regions of Bhārata, this transition is marked through ceremonies in which the young girl receives blessings, new garments, gifts, and guidance from older women. The rituals provide a safe space for conversation on self-care, health, and social customs. Therefore, the ceremonies act as a system of community education as well as rites of passage that concern feminine dignity.
Dharmaśāstras further discuss menstruation within the broader framework of ṛtukāla, the period of a woman's fertility for reproduction. They describe ṛtukāla as a period of sixteen nights from the commencement of menstruation, while identifying specific days during which conjugal relations are discouraged and other days where it is considered as appropriate. These discussions attempt to regulate family life, conception, and reproductive health within the ethical framework of gṛhastha-dharma.
The Śākta tradition understands menstruation as an expression of Śakti, the creative energy that sustains the universe. This belief follows the usual working of the Indian Knowledge System where biological processes are understood with broader spiritual realities. The Śākta tradition in Bhārata observes festivals dedicated to the menstruation of the Devī and Mother Earth.
Fertility, regeneration, and cyclical renewal are understood as expressions of the same cosmic force that operates simultaneously within women, Bhūdevī, and the feminine divine.
As per legend, the Kāmākhyā Mandira in Assam is a Śakti-pīṭha, established where the yoni of Devī Śatī is believed to have fallen on earth. Thus, the presiding goddess, Devī Kāmākhyā, undergoes her annual menstruation cycle in the form of the Ambubācī Melā. Kāmākhyā Mandira worships the Devī as a rock fissure that symbolizes the yoni, which is nourished by an underground spring. During the festival, the temple doors are shut to visitors for three days as Devī Kāmākhyā is believed to be undergoing her annual menstrual cycle. Ritual worship resumes only after a purification ceremony and devotees receive pieces of red cloth symbolic of the regenerative power of Devī Śakti.
Similarly, in Odisha, the Rāja Parba marks the menstrual cycle of Bhūdevī (mother Earth). Agricultural activities, such as ploughing and sowing, are suspended during these days in acknowledgement of the belief that Bhūdevī is undergoing a period of renewal similar to that of the female body. The observance demonstrates the ecological co-relation to menstruation where fertility is not confined to human reproduction but extends to the soil, vegetation, and cyclic regeneration of nature itself.
These observances reflect on how Bhāratīya festivals integrated the biological rhythms of women, nature, and the cosmos. The festivals and texts reinforce the belief that the idea of fertility, regeneration, and cyclical change are integral to human life. The temporary cessation of ritual worship or agricultural activity during these periods reflects the reverence for cycles of renewal rather than a pattern to undermine/ misconstrue the sacred feminine divine.
Modern Relevance
Contemporary discussions on menstruation often focus solely on hygiene and reproductive health, while the Indian Knowledge System complements these practices by integrating physical well-being with cultural values and community life. The emphasis on rest, the celebration of menarche, and the festivals centred around menstrual cycles of the divinity emphasise how Bhāratīya civilisation did not isolate the biological from the cultural or spiritual.
The holistic framework of Bhāratīya society ensures the interconnectedness of body, society, nature, and the cosmos, such that every aspect of human life is understood in totality. Viewed through the framework of the Indian Knowledge System, menstruation becomes a point of convergence of medicine, ritual, ecology, and philosophy. It underscores the civilisational understanding in which the body is not isolated from prakṛti but participates in the interconnected order of cosmic rhythms.
Conclusion
The multi-dimensional approach towards female reproduction demonstrates the integrated methodology of Bhāratīya civilisation where biological realities were never detached from ethical and social responsibilities or spiritual inquiries. The Indian Knowledge System understands menstruation through the interconnected principles of ṛtu, ṛta or vāyu. Āyurveda, dhārmika, and Śākta traditions approach the menstrual cycle or ṛtudharma via medical, scientific, ritual, cultural, and cosmic aspects that go beyond just contemporary women’s health care. They honour the reproductive capacity of females through traditions, rituals, and social customs.
Bhāratīya framework’s holistic perspective of ṛtudharma continues to offer important insights into women’s health and cultural continuity. Hence, viewed through the lens of the Indian Knowledge System, menstruation is understood as more than just a biological event. Ṛtudharma links the body, nature, health, and spirituality to reflect a holistic worldview in which well-being, cultural practices, and cosmic rhythms remain deeply interlinked in Bhāratīya society. It accurately represents the characteristics of civilisational thought and character of Bhārata’s society as a whole.
