God is under the influence of love and He has this rule- as much as you love me, that much I will also love you. If you say-"O God! you do not have any personality, you are just light", God will say, "Alright, I will meet you as light." If you say-"No God, I am not satisfied with light, I want to see you and I want to witness your Divine pastimes, and tie you up with a rope, and take care of you like mother Yashoda", God will say, "Alright, then I am your child."
God has this rule that whichever soul loves him at whatever time to whatever extend in whichever bhav; God will love the soul back at the same time to same extend with the same bhav.
In this episode, Swami Mukundananda explains beautifully this law of God with examples and quotes from the scriptures.
