I had to read this twice now to begin to understand what Parthasarthy means for us to understand.
Attachment, the mind, and desires keep us from realizing the Self. Developing our intellect - learning to control our mind and discerning how to experience emotions, love without attachment, and taking the middle path guide us toward enlightenment.
I think my favorite part is about the waker, the dreamer, the deep-sleeper, and You. We are not our waking consciousness, our dreaming consciousness, or our nothingness of deep-sleep, we are something higher. Identifying with one experience is not whole because those experiences are conditioned, and that is something really profound to start seeing as True.
I'm thinking about this now in the realm of healing. People are born with certain "conditions" and the processes and experiences that are manifested because of their conditions guides people to be unconditioned, to bring them closer to the Self. Woof.
What I don't understand is this push to become absent of desires.
