Within the vision of Niyamasara, Ashta-samyama is presented as a graded discipline of eight restraints through which conduct is progressively purified and the soul is prepared for liberation. These restraints are not merely external rules but inner modes of self-mastery that touch sensation, bodily needs, activity, and the subtle movements of passion and attachment. Each restraint narrows the field of worldly entanglement and opens a corresponding space for equanimity and clarity. Taken together, they sketch an ethical path in which the aspirant learns to remain inwardly undisturbed while still moving through the conditions of embodied life.

The first two restraints concern the most immediate experiences of embodiment. Vedanā-samyama is restraint toward pleasure and pain, the capacity to endure pleasant and unpleasant sensations without clinging to one or recoiling from the other. Closely allied to this is Kṣudhā-pipāsā-samyama, restraint of hunger and thirst, in which bodily needs are borne calmly, without impatience, anxiety, or greed. In both cases, the ordinary reflex of craving and aversion is gently but firmly checked, allowing a more even, unreactive awareness to emerge.

The next pair of restraints turns to the field of worldly engagement and possession. Ārambha-samyama is restraint in undertakings and activities, a deliberate limiting of worldly enterprises and the violence and restlessness that often accompany them. Parigraha-samyama is restraint of possessions, curbing acquisitiveness and loosening attachment to wealth, objects, status, and relationships. Through these disciplines, outer life is simplified and the subtle bondage of “mine-ness” is weakened, so that action can proceed with less entanglement and more inward freedom.

The fifth restraint, Krodha-ādi-samyama, addresses the core passions—anger, pride, deceit, and greed—by weakening and controlling these inner defilements. This naturally prepares the way for Śarīra-samyama, restraint of the body, in which physical movements, posture, and actions are disciplined to avoid harm and restlessness. Indriya-samyama, restraint of the senses, extends this discipline to sights, sounds, tastes, smells, and touches, checking the tendency of the senses to scatter attention outward and fuel desire.

Finally, Prāṇa-samyama, restraint of the vital forces, gathers the entire discipline into a subtler interior stillness. By steadying and pacifying breath and life-activity, the aspirant supports meditation and detachment, allowing the other restraints to mature into a stable disposition rather than a temporary effort. In this way, Ashta-samyama, as described in Niyamasara, functions as an integrated ethical and contemplative framework: beginning with endurance of sensation and care of the body, it culminates in a quieting of the very currents of life that ordinarily drive one toward bondage, thereby preparing the soul for liberation.
