In the usual way that we teach this path, we work first with our individual consciousness, its structures and limitations and its properties of freedom and flow. In doing so, we explore the various essential qualities that are part of its nature; we see the ways in which true nature manifests itself within and through the individual consciousness. As our experience and perception become more subtle, we discover and explore the boundless or formless dimensions of true nature, moving from one dimension to another, each one adding more understanding, more realization, and more subtlety to our experience of our true nature and of reality and the world. Throughout this entire process, the self is challenged in various ways as realization continually chips away at the ego identifications. We can change from being the self to being true nature itself. In boundless or nondual realization, we know our true self as being true nature as well as being everything, being the ground and the nature of everything. – The Alchemy of Freedom: The Philosophers’ Stone and the Secrets of Existence, Ch. 3
