Answer: A young man is walking down the street and glowing with happiness. Why? He loves a girl.
Tell me, what does he get from this love? Why does this feeling fill him so much? What does he receive? He doesn’t receive, but is ready to bestow. He wants to unite with her, to love. I am not talking about love between adults, about sexual relations, but about a higher feeling, even though it is also based upon reception.
You love a person and want to do something pleasant for him. You want him to be happy and aspire to unite with him.
Besides hormonal attraction, which even animals experience, we received such an exalted feeling so that we would learn something from it. After all, nothing was created in vain. That is why in our biological organism, in this protein body, there is a certain inspiration from this kind of feeling for the neighbor, called love of one person for another.
Why does this fulfill me? Feelings fill us. Love is filled by the fact that I exist in bestowal rather than reception. And if I receive something from someone who loves me, then it’s only to awaken me to respond to the Light. But in essence, if love lives inside of me, then I enjoy by bestowing to the person I love, without receiving from him.
This is a law of nature and nothing can be done about it.
