Answer: Living in this mortal world, you will exist for a certain number of years and then abandon it, leaving practically nothing but some garbage, just like each and every one of us in this earthly life. Kabbalah teaches that in this life, in this world, in our time, you can attain the spiritual world, as if you are already above our world, absolutely not leaving it, not dying.
You simply neutralize your egoism that depicts this world to you and start seeing the world of forces and properties called “the spiritual world.” When you reveal it, you can exist in it even today, control our corporeal world from there, and live in the two worlds simultaneously.
In this case, the death of your body will not be something tragic, unexpected, or special for you because while living in this world, you are in contact with your eternal part, with the soul. And then you will rise in your understanding, in the revelation of the soul higher and higher. Therefore, it is desirable to at least a little, in some way, adhere to your eternal part.
