A concise introduction to the nature and purpose of meditation through Padmasambhava's Tibetan Book of the Dead: “The Introduction to Awareness" or “Natural Liberation through Naked Perception.” 

Meditation is an exercise to develop consciousness to its full potential.  Awareness and directed attention are the basis of meditation, especially as described by the originators of every genuine religion. This lecture outlines the three vehicles of any spiritual school, their methodologies and meditative disciplines, while comparing esoteric Buddhism to the Hebraic Kabbalah: the Tree of Life.  You will also learn the profound dynamics and interdependent relations of spirit, consciousness, will, mind, emotion, energy, and matter.
