Niyamasara presents ahimsa as the very heart of spiritual discipline, insisting that non-violence must permeate thought, word, and deed in a unified way. The text gives primacy to the inner state: violence is rooted first in intention, in mental tendencies such as hatred, anger, greed, and ill-will, while physical injury is secondary when compared to this inner disposition. Thus, genuine non-violence is not exhausted by refraining from outward harm; it is a process of purifying the mind so that the very wish to injure any living being falls away. In this sense, ahimsa becomes both an ethical rule and a mode of inner transformation that prepares the soul for liberation.

At the level of thought, Niyamasara calls for the abandonment of hostile or cruel mental states and the deliberate cultivation of compassion, benevolence, and equanimity toward all forms of life. Entertaining schemes of harm, even if never acted upon, is seen as a subtle form of violence that binds the soul. The text therefore encourages a vigilant awareness of one’s inner landscape, so that anger, delusion, and other passions that give rise to violence are steadily weakened. Non-violence in thought becomes a discipline of replacing impulses to dominate or injure with attitudes of friendliness and care.

In the realm of speech, Niyamasara teaches that words themselves can wound and thus participate in violence. Speech that is harsh, malicious, abusive, or that incites others to harm is rejected, even when it may be factually correct. The ideal is truthful, gentle, and restrained speech that avoids causing distress and does not encourage violent action in any way. Silence is preferred to any utterance that would disturb or injure another, and speech is to be used as a means of fostering peace and non-violence rather than contention.

Regarding bodily action, the scripture demands abstention from harming any living being, extending this concern even to the smallest and least perceptible forms of life. Direct killing, injury, or torment are clearly prohibited, but so too is supporting, condoning, or materially enabling acts of violence. This leads to a carefulness in movement, livelihood, and consumption, so that harm is minimized as far as possible. Through this threefold discipline of body, speech, and mind, ahimsa becomes the central path of karmic purification and the indispensable foundation for progress toward spiritual freedom.
