Answer: The meaning of reincarnation for us is the gradual accumulation of feelings and sensations that will make it possible for us to reach a new level of consciousness, knowledge, and feeling of all of creation, of the Creator, of the power that fills everything.
Thus we can truly become a person of the highest state and not remain as we live today, as an animal that perceives the world only through our physiological body, i.e., through the property of reception. Rather, we will feel the world through a new, spiritual body, through the property of bestowal and love.
This is the meaning of reincarnation: the accumulation of a sufficient quantity of sensations in order to exit our world for the upper world.
