Quote from : The Way of the Explorer: An Apollo Astronaut's Journey Through the Material and Mystical Worlds Book

The desire to live life to its fullest, to acquire more knowledge, to abandon the economic treadmill, are all typical reactions to these experiences in altered states of consciousness. The previous fear of death is typically quelled. If the individual generally remains thereafter in the existential state of awareness, the deep internal feeling of eternity is quite profound and unshakable.
