This work is being presented in three parts. Although each section stands alone, yet they are all inextricably intertwined. The intention of the author is to furnish those for whom Marijuana is The Perennial Teacher with a decipherable experience of spiritual fulfillment as it is implemented in The Marijuana Consciousness. The Yoga of Marijuana gives the basic philosophical and historical underpinnings of The Science of Yoga, including the intentionally hidden, ancient and originating connection to The Marijuana Consciousness. The reason that the obvious synchronicity between these two paths has always been denied by the establishment will be explained as well as how and why the primordial Practice of Marijuana as an esoteric discipline is re-emerging with such power at this moment in time in this materialistic period of civilization. The book explains the enhancement toward the uncovering of consciousness that is not only a possibility through the Yoga of Marijuana but is, in fact, an ongoing, although little known, abiding reality. In addition, the work will clarify how Marijuana serves as proactive and perennial guide on the Path to Enlightenment as reflected in and precedent to Classical Yoga as it comes down to us from the primordial and secret Tantra. It is the aim of this introductory section to spark the interest of those for whom the Marijuana Consciousness is of utmost importance and to prepare the way for recognition and reception of The Yoga of Marijuana. Part II, The Tantra of Marijuana will present the origin and profound philosophy of the utterly misunderstood Tantric Path as it evolved from the primeval purity of the aboriginal mind. While the comprehensive tolerance and refined practices of Eastern Thought are progressive, profound and far reaching, Tantra is unquestionably the crowning pinnacle of its legacy. Interestingly enough, this prehistoric teaching is considered the most suitable Path to Enlightenment for the distracted mind of the present era, while Shiva, Lord of Bhang fits into the mix as the symbol of conscious pulsation of the universe, in keeping with the most advanced contemporary science. Part III, Marijuana and Yoga Practice will reveal the integration of the specific Yogic training with the underlying principle behind each practice for health and heightened awareness, mirrored in and originating from the subtle Benefits of Marijuana. The hope is for the three sequential parts to coalesce over time in both the cognitive and intuitional faculties and be internalized holographically as a unified reality
