Practice Beyond Substantialism

Patañjali’s achievement is practical before it is metaphysical. The Yoga Sūtra codifies techniques of spiritual cultivation whose efficacy does not depend entirely upon accepting the ontology through which Classical Yoga explains them. Practice, dispassion, ethical restraint, posture, breath control, withdrawal of the senses, concentration, contemplation, and union form a coherent discipline of body and mind.

The commentary therefore separates the enduring value of this discipline from its substantialist interpretation. In Classical Yoga, liberation requires the disentanglement of puruṣa, the permanent and independent seer, from prakṛti, Nature and its transformations. The Buddhadharma rejects such a self-existing principle. It locates ignorance not in the involvement of an eternal self with Nature, but in the attribution of inherent existence to persons and phenomena.

This difference changes the interpretation of liberation. Classical Yoga seeks the aloneness of the seer. Buddhist Yoga seeks the cessation of reification and the suffering sustained by self-grasping. Yet both traditions recognize the need for disciplined attention, ethical preparation, calm abiding, discernment, and sustained personal effort.

The commentary accordingly reads Patañjali neither as unquestionable authority nor as an obsolete representative of Hindu metaphysics. It receives the Yoga Sūtra as a major technical document of contemplative practice while critically examining its account of the self, the Lord, Nature, karma, powers, and liberation.

Book I : Union

The opening book defines Yoga as the restriction of the fluctuations of consciousness. It examines practice and dispassion, seeded and seedless union, devotion to Īśvara, the hindrances to cultivation, and the progressive clarification of consciousness.

Book II : Exertion

The second book identifies the causes of sorrow and introduces the practical path by which they are attenuated. Its eight limbs join ethical restraints and observances with posture, breath control, withdrawal of the senses, concentration, contemplation, and union.

Book III : Powers

The third book examines concentration, contemplation, and union as a single constraint applied to an object. It describes transformations of consciousness, extraordinary powers, and the liberating vision of discernment, while warning that powers may obstruct the final aim.

Book IV : Aloneness

The concluding book treats karma, the formation and transformation of consciousness, the relation between mind and object, and the final separation of seer and seen. The commentary critically examines whether this book belongs to the original textual stratum and whether its substantialist conclusion can be retained.
