Those striving for liberation from old age and death, taking refuge in Krishna, come to know Brahman entirely, the Self, and all action. This verse bridges liberation-seeking and devotion. Shankara sees it as establishing that Brahman-knowledge includes all other knowledge. Ramanuja reads the complete scope — Brahman, Self, and karma — as the fullness of theological understanding necessary for liberation. The bhakti tradition finds that taking refuge in God is itself the method and the result. Madhva explains that Brahman is truly known only through devotion to the Supreme Person. Abhinavagupta sees the desire for liberation from aging and death as the deepest motivation turning consciousness back toward itself. Vallabhacharya teaches that taking refuge in Krishna is itself knowing Brahman, since Krishna is the complete Brahman with all attributes. Tilak validates purposeful effort: the karma yogi strives through selfless action toward Brahman as surely as the contemplative. Vivekananda universalizes: every person who fights against limitation and decay is striving for this liberation, whether they know it or not.
