Love of others can only be through revoking of one’s self (Rabash, Article 1, Part 1, “Purpose of Society—1”)
Self-denial is the annihilation of oneself in relation to others. At the same time, a person does not just disappear, but is engaged precisely in the fact that everything that is in him—in feelings, in thoughts, in actions—he does only for the good of another. This is called love. You exist only for the sake of another.
On the one hand, each person should feel lowly, and on the other hand, be proud that the Creator has given us the chance to be in a society where each of us has but a single goal: for the Shechina [Divinity] to be among us.
That is, so that we return to the original state from which we were created when the Creator began to develop within Himself the desire to receive, the opposite of Himself, in order to create creations. And the creatures must be opposite to Him. And therefore, gradually within the Creator, within the upper light, a desire to receive was created, which then broke into many parts, sub-parts, sub-sub-sub-parts, and so on, along 125 degrees of descent from a single primordial desire, which we call Malchut of Ein Sof (the world of infinity) to our state and even below it.
All this happens by breaking a single desire into a multitude of desires, so that we can begin the return journey, our evolution, our development to begin to reveal the Creator from opposites.
