Once you realize that all comes from within, that the world
in which you live is not projected onto you, your fear comes to an end.
"Prepare yourself for the coming astral journey of death
by riding daily in a balloon of divine perception.
Through delusion you are perceiving yourself as a bundle of flesh and bones...
Meditate unceasingly, that you quickly behold yourself as the Infinite Essence"
~Lahiri Mahasaya, the Guru of Yogananda's Guru
I have no scientific evidence for anything I say.
