Krishna is the knower of everything because He does not see outside in but inside out. Gopinathji sees the Motivations, Intentions & Aspiration within our heart.
Children should make Krishna and his devotees as their best friend, not the Computer.
Krishna is the ultimate purpose of all sacrifice. He is also the enjoyed of all sacrifices; therefore He is known as Yajna-Purusa.
Wherever there is Krishna the master of all mystics, and wherever there is Arjuna, the supreme archer, there will also certainly be opulence, victory, extraordinary power, and morality.
Bhagavad Gita 18.78
The ultimate goal of Bhakti is to get Krishna and we get it by taking shelter of the holy name.
