The Ashtanga Yoga System — Integration of All Eight Limbs
Patanjali's Eight-Limbed Yoga (Ashtanga) is not a sequential curriculum but an integrated, simultaneous practice: all eight limbs support and enhance each other, forming a complete ecology of transformation.
Sutra 2.29 lists the eight limbs (ashtau angani): Yama (ethical restraints), Niyama (personal observances), Asana (posture), Pranayama (breath regulation), Pratyahara (sensory withdrawal), Dharana (concentration), Dhyana (meditation), Samadhi (absorption). These eight are not steps to be completed in order but dimensions of a complete practice engaged simultaneously. The ethical foundation (Yama, Niyama) purifies the practitioner so that physical and energetic practices (Asana, Pranayama) are effective. The physical and energetic practices prepare the ground for sensory and mental practices (Pratyahara, Dharana, Dhyana). All of these open toward Samadhi. A yogi who practices only asana without the other seven limbs is not practicing Patanjali's yoga. The completeness of the system is its genius.
Moral restraint, observance, posture, breath regulation, sense withdrawal, concentration, meditation, and absorption are the eight limbs.
Yoga scholar Mark Singleton's Yoga Body documents how the modern emphasis on asana as the totality of yoga practice represents a radical departure from Patanjali's integrated system — and how the recovery of the full Ashtanga framework, including its ethical and meditative dimensions, transforms asana from exercise into genuine spiritual practice.

Breath regulation is the fourth of eight limbs: after ethics, observances and posture, before sense withdrawal and the three degrees of meditation. Knowing where it sits explains why the text spends so little time on it.
