Lord Krishna said after Karna fired his Sakti weapon at Ghatotkasha that even his Sudarsha Chakra was incapable of stopping the Sakti Weapon. My question is: Why Krishna, being the Lord of the universe, was incapable of stopping a weapon given to Karna by Indra?
An avatar voluntarily chooses not to access all knowledge and power for reasons known best to them. Rajiv Malhotra talks about this in his book:
"The avatar role-plays with deliberate and voluntary self-limitation. The avatar has infinite knowledge which he can choose to access, though ordinarily he does not, or else does so selectively"
I imagine this is applicable in the context of Krishna not stopping the Sakti weapon .
