The Dual Purpose of the Teacher
The role of the teacher is basically twofold: first, to arouse the deepest creative power of Life present within you; then, to support you as this power unfolds. As this happens, the creative power of Life makes you aware of the intimate interrelationship of all spirit and matter, and of the oneness of all spirit. Supported by the teacher, you enter into an experience of union not only with the teacher, but also with that teacher in whom your own teacher is unified, and with the Teacher from whom all things have come forth. . . .
Furthermore, the physical teacher represents both a support and a resource — not a conspiracy to make you bound and dependent. The physical teacher doesn't exist to dominate your life, and no teacher with half a brain would even want to. What would be the point? Instead, the teacher is simply like a well from which you draw a clear, pure vitality which supports the process of your regeneration and transformation. It may take the form of advice, instruction, or a subtle but powerful exchange of energy; all of these are ways in which this fundamental essence articulates its creative power.— Swami Chetanananda, Yoga Gems by Georg Feuerstein
