In this pivotal verse, Lord Krishna explains that the cessation of all worldly suffering is not a result of outward effort or the mere removal of external circumstances, but a natural byproduct of 'prasāda'—the serenity born of divine grace. When the practitioner learns to withdraw the senses from their agitation and rests in the stillness of the Self, the mind becomes 'prasanna,' or transparently pure. This tranquility is the fertile soil where true wisdom takes root. Without this inner clarity, the intellect is constantly buffeted by the winds of desire and attachment, which are the fundamental causes of all human anguish. Philosophically, this verse marks the transition from the struggle of self-control to the effortless abiding in Brahman. Krishna teaches that when the heart is no longer clouded by the turbulence of egoic reaction, the intellect (buddhi) stops wavering. It becomes firmly established in the light of the Absolute. This is not a passive state, but a dynamic, enlightened alertness where the seeker no longer identifies with the passing show of worldly sorrows. It is the realization that the Self is inherently separate from the suffering mind, a state where grace dissolves the distance between the seeker and the Sought.

True inner stability is not forced by discipline alone but arises when divine grace purifies the heart, allowing the intellect to anchor firmly in the eternal stillness of the Self.
