CC Madhya 15.51

ki kāya sannyāse mora, prema nija-dhana
ye-kāle sannyāsa kailuṅ, channa haila mana
Word for word: 
ki kāya — what business; sannyāse — in the renounced order; mora — of Me; prema — love; nija-dhana — My real wealth; ye-kāle — at which time; sannyāsa kailuṅ — I accepted the renounced order; channa — deranged; haila — was; mana — mind.
Translation: 
“I had no business in accepting the renounced order and sacrificing My love for My mother, which is My real property. Actually I was in a crazy state of mind when I accepted sannyāsa.
