“Learning to love yourself, is the greatest love all”

"Nature Boy" (1948)
The greatest thing you'll ever learn is to love and be loved, just to love and be loved.
His assertion to Joe Romersa, of how his lyrics should be corrected, saying that "To be loved in return, is too much of a deal, and that has nothing to do with love."
Context: While we spoke of many things
Fools and kings
This he said to me:
"The greatest thing you'll ever learn
Is just to love and be loved in return."

Context: Before he can know Who he is, man has to unlearn the mass of illusory knowledge hehas burdened himself with on the interminable journey from unconsciousness to consciousness. It is only through love that you can begin to unlearn, and, eventually, put an end to all that you do not know. God-love penetrates all illusion, while no amount of illusion can dim God-love. Start by learning to love God by beginning to love those whom you cannot. You will find that in serving others you are serving yourself. The more you remember others with kindness and generosity, the less you remember yourself; and when you completely forget yourself, you find me as the Source of all Love.
