Lord Krsna and His abode exist, and one can go there, reach Him, and associate with Him. That is a fact. Spiritual life means to be in
association with the Supreme Lord and to exist in bliss and knowledge eternally. Such eternal association means to play with Krsna, to dance with and love Krsna. Or Krsna can become your child — whatever you like.
