To exit into spirituality is the same as to levitate above the earth in our world. You cannot just suspend yourself in the air. This requires a force that will hold you despite the force of gravity. Gravity is the force of our egoism. It always pulls me down; hence, as soon as I forget about the goal, I immediately fall to the ground.
If I wish to unite with the others, prior to anything else, I must put forth constant effort in order to “hang in the air,” in aspiration to unity. There is no cutting slack in this case: The instant I forget, I fall.
That’s why caring for the others will never become a habit or a second nature. And we should be thankful for it since thereby, we get a chance to realize our free will every next second.
If it were habit that moved me, I would be an angel. An angel obeys its nature: the nature of bestowal. It hangs in the air because it is “lighter than air” and isn’t affected by the force of earthly egoistic gravity. But a human being is.
