How safe is it to have a transcendent experience?

If done through proper channels, a transcendent experience can become something which is profoundly moving and enhances the human spirit. If proper preparation is not done however, it may create disturbances in the psyche which is why drugs should never be used in opening the doors of perception. Meditation is a far more effective, holistic and long lasting method of achieving and integrating transcendence, if and when it occurs.
