The shared philosophical foundation

Both Yoga and Ayurveda emerge from the same Vedic knowledge tradition and share the Samkhya philosophical framework. The Pancha Kosha (five sheaths) model describes the human being as five nested layers: Annamaya Kosha (food/physical body -- the domain of Ayurvedic diet and herbs), Pranamaya Kosha (energy/breath body -- the domain of Pranayama), Manomaya Kosha (mental body -- the domain of meditation and Yoga Nidra), Vijnanamaya Kosha (intellect/witness body), and Anandamaya Kosha (bliss/causal body). Classical Ayurveda addresses primarily the first two Kosha; classical Yoga addresses all five progressively.

Constitutional Yoga practice

Vata constitution -- grounding, warming, steady

Vata requires: slow, steady, warming, and grounding practices. Short (30--45 minute) sessions. Repetitive sequences (same sequence daily provides the Vata nervous system with the stability it requires). Emphasis on standing poses (grounding), forward bends (calming Apana Vata), and gentle twists. Savasana for at least 10 minutes. Avoid: rapid sun salutations, vigorous jumping transitions, excessive variety, hot yoga, and practicing when hungry or fatigued.

Pitta constitution -- cooling, surrendering, non-competitive

Pitta requires: cooling, moderate-intensity, non-competitive practices. Emphasis on hip openers, forward bends, and lateral stretches. Moon salutations over sun salutations in hot seasons. Pranayama: Sheetali, Sheetkari, Nadi Shodhana. Avoid: Bikram/hot yoga, competitive or performance-oriented practice, Bhastrika and Kapalabhati (too heating), and practicing in hot midday. The primary Pitta Yoga error: competitive comparison and ego-driven practice that aggravates Pitta regardless of the physical form of the asana.

Kapha constitution -- vigorous, varied, challenging

Kapha requires: vigorous, heating, varied, and challenging practices. Vigorous sun salutations, inversions, backbends, and chest openers (counteracting Kapha's natural tendency toward closure). Sessions of 60--90 minutes. Pranayama: Bhastrika, Kapalabhati, Ujjayi. Kapha needs to be challenged to benefit -- gentle restorative Yoga practices that a Vata or Pitta constitution finds therapeutic will simply confirm Kapha's natural inertia.

Ashtanga Hridayam, Sutrasthana 2.11
Vyayamam kurvato nityam viruddhamasanam tyajet -- One who exercises (practices Vyayama) daily should avoid incompatible postures. The incompatibility is determined by constitution -- what is appropriate Vyayama for one constitution is Viruddha (contraindicated) for another.

Classical Asana documentation

Classical Ayurvedic texts do not document specific Asanas (postures) in the way that Yoga texts like Hatha Yoga Pradipika or Gheranda Samhita do. What Charaka Samhita and Ashtanga Hridayam document is Vyayama (physical exercise) by quality -- its Dosha effects, the half-capacity rule (Ardha Shakti), and the principle that exercise should produce Hrit Drava (sweating at forehead, nose, and joints) without crossing into depletion. The mapping of specific Asana practice to these classical Ayurvedic principles is a contemporary Ayurveda-Yoga integration, not a classical documentation -- this distinction is important when evaluating claims about 'Ayurvedic Yoga.'

Therapeutic Yoga -- the practitioner's role
Yoga as therapy (Yoga Chikitsa) -- the use of specific Asana and Pranayama to treat specific conditions -- requires both Yoga teacher training and Ayurvedic assessment to prescribe correctly. A Yoga teacher without Ayurvedic assessment cannot correctly individualise to Dosha; an Ayurvedic practitioner without Yoga training cannot correctly assess and cue postural practice. Therapeutic Yoga for specific conditions (post-surgery rehabilitation, chronic pain management, mental health conditions) benefits from the combined assessment.
