The "great void" mentioned in my book is not synonymous with death. Death conveys the idea of the loss of consciousness. There is no loss of consciousness in this state, but the consciousness is transformed indescribably. The state is so blissful, moreover, that there is no worrying about the loss of the ego. However, it is a temporary state because so long as we are living in the flesh we are unable to sustain it and are drawn back by the forces of nature--first to the ego and then to the body. But anyone who has been through that experience even once cannot possibly regard the ego and the body ever again in the same way, because their limitations are clearly felt.
In any case, one need not worry about this absolute condition but rather should await its arrival--then judge whether it is worthwhile or not.
