Answer: The search comes down to the fact that a person looks for a way to discover eternal life: either by changing the world or by changing himself.
According to Kabbalah, the two options, which seem different at first glance, merge into one as by changing the world you change yourself, and by changing yourself you change the world. It is the same thing.
When you change yourself, you enter a level where you begin to perceive the world as eternal and whole. Eventually you attain a perfect eternal life. It is destined for us while still on the level of this world, and then you can quietly and peacefully detach yourself from your corporeal body that is on the animal level.
Question: Does this means that a man can live forever?
Answer: I don’t know what you mean by “man.”
A person’s inner self exists forever, beyond time. There isn’t really the concept of “forever” in the spiritual world because this is also a way of determining time, and when you write “t=,” it is simply infinity. This is the reason that we speak about life above time.
