That reciprocation of the Lord comes by the efforts that we make throughout this life. The biggest endeavor that we have to make throughout this life is to remember Krishna. It is very difficult to always remember Krishna. Thus He said to Arjuna in the Bhagavad-gita, “If you cannot always fix your mind upon Me, then follow the regulative principles of bhakti-yoga.” By following the regulative principles of bhakti-yoga, we will develop a desire to come to Krishna. To follow the regulative principles of bhakti-yoga means that each day we must be engaged in those activities that help us remember Krishna.
