[Discourse 27 - p.470-471] .... Yogis enhance their great spiritual power and realization by a natural, not suppressed, conservation of the vital essence, transmuting it into divine vibrations in meditation that awaken the higher centers in the spine with their exalted states of consciousness.
~Paramahansa Yogananda
That explicitly implies high s(exalted) states of consciousness
This has really been a part of my thoughts for most of my life but much more lately; that is how do we come to higher or more expanded states of awareness. i believe just the thought-the desire-as it gets stronger leads us in the direction to attainment and expression of such states.
Our spirit guides and gurus expose us to these states of awareness and point to how we can manifest them.
