Saucha
Purity
Definition
Saucha is the practice of purity and cleanliness at all levels: physical, mental, and energetic. As the first niyama (observance), it establishes the foundation for the more subtle practices that follow.
Etymology
It derives from the Sanskrit root śuc, which means “to shine,” “to be pure,” or “to be clean.” Saucha is the state of purity or cleanliness that allows the inner light to shine without obstacles.
Context in the Yoga Sutras
Patañjali presents saucha in Sutra II.32 as the first of the five niyamas. Sutras II.40-41 describe its fruits: śaucāt svāṅga-jugupsā parair asaṃsargaḥ — “From saucha arises detachment toward one’s own body and absence of impure contact with others”; and sattva-śuddhi-saumanasya-ekāgrya-indriya-jaya-ātma-darśana-yogyatvāni ca — “Also purity of sattva, mental cheerfulness, concentration, mastery of the senses, and fitness for the vision of the Self.”
These sutras reveal a paradox: by purifying the body, we become less identified with it, not more. Cleanliness leads to detachment.
Practical Application
Physical purity:
- Regular personal hygiene
- Nutrition that nourishes without intoxicating
- Clean and orderly environment
- Shatkarmas (cleansing techniques of Hatha Yoga): neti, dhauti, basti, etc.
Mental purity:
- Observe and reduce negative or harmful thoughts
- Consciously choose what information we consume
- Avoid conversations that contaminate the mind
- Cultivate thoughts that elevate
Energetic purity:
- Prāṇāyāma to cleanse the subtle channels
- Time in nature
- Adequate rest for the body to regenerate
Purity in relationships: Danilo Hernández notes that saucha includes maintaining relationships free of manipulation, deception, or hidden intention. Relational purity is transparency.
Relationship with Yoga Practice
The Hatha Yoga tradition places great importance on saucha. The Bihar School of Yoga teaches that cleansing practices (shatkarmas) prepare the body for more advanced āsanas and prāṇāyāma. A body laden with toxins makes concentration and energy flow difficult.
In āsanas, the practice itself has a purifying effect. Conscious movement stimulates circulation, facilitates elimination, and releases accumulated tensions. Certain postures (twists, inversions) have specific cleansing effects on internal organs.
In prāṇāyāma, techniques like kapalabhati and bhastrika are explicitly purifying. Nadi shodhana cleanses the subtle energy channels.
In meditation, saucha manifests as the mental clarity that allows concentration. A mind agitated by impure thoughts cannot sustain itself at one point. The gradual purification of mental contents is a prerequisite for deep meditative states.
