From G and my response,
Can I ask about Self-awareness, Being, "I"...all of this. "Self-Enquiry" brings you to the I-thought, which will bring it back to the heart. This will eventually destroy the I am the body, the I-thought...the ego.
Don't make it so complicated. I-thought is a fiction, only Am is. Staying in the sense of existence--or the feeling I--will get you to the same place--knowledge first hand that you are beyond the body and world.
Staying in the self, or Self-Awareness as much as you can through self-Enquiry or through other means, I have difficulties in understand what are the best ways to do this. Especially following the "I" to it's source, the right side of the heart.
Absolutely forget the heart. That was a ruse by Ramana to turn people inward. The real inward is not into a place in the body because the body does not exist as an independent entity, rather go into That which cognizes and is aware, the sense of I, or the unformed matrix of Am-ness. Just resting in self, going deeper into silence to its deepest level. Everything in the world is just “noise” added onto your true nature. Some go into that silence by “looking” within, others by “feeling” in, sort of falling backwards into your true self.
Briefly, How to get the I-Though to go back at the source...the heart.
How to stay in Self-Awareness.
You don't get the I-thought to go back to the source. Concentrating on the I-thought makes it real. Ask once "Who am I?, look within and do nothing more. Repeat every minute or two. After a while, the minutes will stretch into many minutes. Just keep going. You want to attend to where the I-thought comes from, not the thought itself.
FORGET ABOUT THE HEART.
