You think of Krishna and Krishna will think of you.
Krishna consciousness means Samadhi. One should always be absorbed in thinking of Krishna. How He eats, walks, what He does. Every day we should practice. Then Krishna will be always thinking of us.
If a child does something wrong, father will criticize and punish the child, but later forgives him, and takes him near him. If ordinary material parents can be so loving towards the child, then what to speak of Krishna and His representative!
Devotee means always in ‘tanmayata’ absorption. Acharyas say that Devotee’s whole life is nothing but Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare, Hare Rama, Hare Rama, Rama Rama, Hare Hare.
