The masters have experienced that they acquired a higher degree of Love by giving Love and being it, not by getting or forcing it. That is why Christ advised us to love your neighbor as yourself.
Christ knew his All-Source and knew that he had radiated it to divine Light by loving all life.

-Because you must be able to love mankind; and then the universe, every animal, every flower, every tree, everything, life, night, light, clouds, the lightning and the thunder. Everything was born through you. Did you know that? And you must love that, you let that live. And that speaks to you. Can you feel that consciousness? And then that love; it is spatial, it is kind-hearted, just. And then you are carried.
