Belief is a deception you play upon yourself.
There is great difference between trust and belief. Trust is personal, Belief is social.
The only way to know something absolutely is to experience it for yourself; anything less is theory, speculation, and belief. .
Unless you become alert and aware in life, unless you change the quality of your living, you will not die consciously. And only a conscious death can bring you to a conscious birth; and then a far more conscious life opens its doors.
