Love for God, spiritual love is actually the food, it is the life, and it is the essence of Lord Jesus Christ.  He is enjoying the nectar of devotion to the Supreme Father, the Supreme Personality of Godhead.  That nectar of devotion, love for God, therefore is what he is telling us, "This is what you must also have.  What I have, you should have that.  What I am doing, that is what you must do.  What I have is the loving service of the Supreme Lord.  My first and foremost commandment is to love the Supreme Lord with all your heart, your mind, your entire being. The second commandment is, you love others as much as you love yourself, and as much as you care about yourself you care about others." This is love.

There was an interesting statement by Dr. Penfield. Dr. Wilder Penfield was not an ordinary materialistic scientist. He, his point, he was a neurologist, neurosurgeon. He probably did more experimenting on the brain than any person uh, in history, uh, live patients, live human patients. So, he ultimately came to conclude at the end of his work, at the end of his life he concluded that the uh brain is not the controller, that the brain is like a computer. That the mind, he's calling the mind, he- he, - he's saying that the mind uses. Instead of saying self, he's saying mind. So he's saying the mind, which is really you, uses this computer the brain, okay? So he wasn't identifying the person with the brain, okay? He wasn't identifying the mind with the brain. But even Penfield did not understand, huh? Even Penfield's understanding was not perfect, huh?
