Out of Body Travel Methods and Benefits is a talk by Allen Feldman about methods of how to leave the body or false self and move as pure soul our true self a spark of God. He goes into detail about the importance of out of body travel and why it is so important to one's spiritual growth.
The wisest saints of in nearly all paths and religions secretly or publically practiced visiting heaven. And reported their findings from these journeys to heaven in what has become among most religions of the world what their insights are based on. "Heaven" itself has been the topic of interest to people for well beyond hundreads of thousands of years.
The difference reminds me what Depak Chopra once said, "Religion is believing in someone else's experience and spirituality is having your own experience." If a student attempts to live the path of the secret teachings as a religion he will make little if any progress spiritually. It is Not a religion. Instead students who make the most progress focus on having their own out of body experiences of heaven.
This is the foundation upon which all direct contact with the pure light and sound that eminates from God is built upon: direct experience instead of relying on the opinions of man which are often questionable. Instead of the false self of flesh we are relying upon something far greater, the VARDAN divine spirit ITSELF, which is that voice of light and sound flowing from HURAY, God.
