Question: Are there forms of life in the universe other than the material world? What does Kabbalah say about this?
Answer: You can stop searching! There are no other forms of life in the entire universe. We are unique in this small world.
All we must do is unite as quickly as possible until we reach the minimal spiritual level in order to ascend to the next dimension.
When a person ascends to the next dimension, the entire universe disappears and fades away, and he enters the world of forces, leaving the world of matter.
