Structural Factors

Shared Core Claims

Shared Methods

The school uses sutra commentary, ethical discipline, meditative training, concentration, breath and sense regulation, phenomenological introspection, and practical soteriological instruction.

Shared Lineage

Yoga inherits ascetic, Upanishadic, and meditative traditions, is philosophically paired with Samkhya, and is classically organized through Patanjali, the Yoga Sutras, the Yogabhashya, Vyasa, Vachaspati Mishra, and Vijnanabhikshu.

Shared Problems

Central problems include mental fluctuation, affliction, karma, rebirth, liberation, embodied discipline, yogic perception, the relation between purusha and prakriti, and the role of Ishvara.

Shared Vocabulary

Key terms include citta, vritti, nirodha, abhyasa, vairagya, klesha, karma, samskara, samadhi, ashtanga, yama, niyama, asana, pranayama, pratyahara, dharana, dhyana, kaivalya, purusha, prakriti, and Ishvara.

Defining Axes

Yoga is defined by citta-vritti-nirodha, the dualism of purusha and prakriti, the eight-limbed path, discriminative knowledge, samadhi, kaivalya, and a theistic Samkhya role for Ishvara.

Method

Method centers on practice and dispassion, ethical restraints and observances, bodily and respiratory stabilization, sensory withdrawal, concentration, meditation, absorption, and commentarial analysis.

Lineage

The lineage runs from Vedic and Upanishadic ascetic practices through Samkhya-Yoga synthesis, Patanjali, Vyasa, Vachaspati Mishra, Bhoja, Vijnanabhikshu, Vedantic and hatha traditions, and modern yoga philosophy.

Subject Focus

Yoga focuses on philosophy of mind, metaphysics of self and nature, ethics of discipline, meditation theory, liberation, religious practice, embodied attention, and the psychology of suffering.

Geography / Culture

Yoga developed in South Asian Sanskrit intellectual and religious settings and later circulated through Hindu, Buddhist, Jain, Vedantic, tantric, hatha, colonial, and global modern contexts.

Historical Reaction

Method

The school proceeds by disciplined practice, progressive concentration, commentary on aphoristic sutras, analysis of mental states, and soteriological testing through contemplative transformation.

Internal Debates
