The one who knows Me as aja, anadi, and loka-maheshvara — undeluded among mortals — is released from all papas. Three predicates of Krishna: aja, unborn; anadi, beginningless; loka-maheshvara, sovereign of all worlds. Together they identify Krishna against every other category.
Shankara reads the verse cleanly. The one who knows Krishna as aja — without origination — and anadi — without beginning — and as the supreme sovereign of all worlds — that person, asammudha among mortals, is released from all accumulated actions. The release is not earned; it follows from the recognition of Krishna's unique standing. The papa is the karma-residue; once the inner orientation has located Krishna correctly, the residue does not bind.
Madhusudana reads the predicates structurally. Because Krishna is the cause of all, he has no karana — hence anadi. Being without beginning, he has no birth — hence aja. Whoever knows Krishna as birthless, causeless, the supreme lord of worlds, stands undeluded — moha-varjita — and is freed from all sins, even those performed with deliberate intent.
Ramanuja reads the predicates with characteristic specificity. Knowing Krishna as unborn distinguishes him from inert matter and from bound souls whose birth is karma-produced. Knowing Krishna as anadi distinguishes him from liberated souls, who are birthless but whose birthlessness was preceded. Loka-maheshvara distinguishes him from each candidate that could otherwise compete for sovereignty. Each predicate does discriminating work.
Madhva reads the verse on the bheda-frame: Krishna is anadi because he is the initiating mover and the origin of all — precisely because he is aja. Knowing this eternal distinction between the Lord and all other categories is itself the moksha-sadhana for the eternally distinct jiva.
Vallabha reads Krishna as aja precisely because even mantra-drashtris cannot grasp his origin; what arises — akasha, jivas, Hiranyagarbha — arises from him, not he from anything.
Shridhara reads the verse cleanly: the cause of all has no cause; thus anadi; without beginning, aja; whoever knows is asammudha and papa-free.
