We are not these egos, small, separate selves, separate identities, but we are in fact, impersonal consciousness, the same one consciousness that is in everyone, it is not personal. Therefore, there is no fear or suffering when you identify with who you really are. As long as you continue to identify with the small, fictionalized self then you are subject to fear and suffering.
The biggest fear is your own death. But when you know your true nature, that of impersonal consciousness, then there is no fear of death, for you were never born and will never die, you are eternal, where is there for you to go, you are beyond space and time, in fact, they exist within you, not you within them.
