Guruji, in Mahabharata Krishna supported both Pandavas and Kauravas. Why did he not lift a weapon in support of Pandavas where as he send his whole army to Kauravas?
Krishna has his own ways, most mysterious, you can't understand. Better give up. Whoever is trying to understand Lord Krishna doesn’t, different people, different groups see different aspects of Sri Krishna. That is why he is called Purna Avatara, he is so complete from every side. Very, very unique.
