In this lecture we’ll explore the Theosophical view of the “Mystery of Consciousness” as the path taken by the human monad from the moment of emerging from its state of absorption (state of rest or Pralaya) within the One. This state of absorption is described as universal unconsciousness. When the human monad emerges, acquiring or manifesting its Mental Principle (Manas), it experiences consciousness of the Self or Ego. But what comes next? What is the end-game of human existence? To answer this question, we’ll follow the Monad’s journey as outlined in Helena P. Blavatsky’s The Secret Doctrine. We’ll see that once Manas is active in us, it becomes by necessity dual - Higher and Lower Mind - another mystery, as at times we seem lost in a world where duality reigns. Lastly, we’ll find in the mystical little book, The Voice of the Silence, how Theosophy puts all this together, showing the road that leads to the Path of Illumination. 2021.
