When you die, your physical body and your physical mind are left behind. But the astral body travels with you, with the mind, with all the remembrances of the past life and the body, remembering all the scars and the wounds that have happened to the physical body. This abstract phenomenon travels with you; hiding within it is your ultimate, existential center.
Until you know the center, you will have to travel continuously from one body to another body. You have been traveling already for thousands of lives, gathering more and more memories in your astral mind, more and more memories in your astral body. Although your center is unaffected, it is surrounded by the astral body, and the astral body goes on from womb to womb, from grave to grave. That is your individuality; it has a continuum. But the continuum comes to an end when you become a buddha.
When you penetrate deeply to the center, you are also cutting the astral body apart, making a way through the mind, beyond the mind, through the astral body and beyond the astral body, to the center of your being. Once you have reached to the center of your being, the continuum of your individuality stops. Now begins the universal existence. You will not enter into another womb again, and you will not be burnt on another funeral pyre again. Now you will be one with the whole.
