Question:

You realized the “truth” (I am referring to the permanent shift of consciousness you have achieved) with no help from others. Do you know of anyone who achieved the same by following your teaching through books/tapes?

.

Answer:
for most people, the shift is not a single event but a process they undergo.  It is a gradual disidentification from thoughts and emotions through the arising of awareness.  Many people, through coming into contact with the teaching, are now undergoing this process, and some are already free.
