Look, the path to Self-Realization is simple, but not usually that easy. There are so many misconceptions to overcome, about who you are, and all the books about spiritual truths that bring in complicated states, abstract concepts, koans, sutras, exotic practices, rumors, etc., all of which block Self-Realization because they focus on the level of understanding--the mind. The mind is the wrong instrument for understanding. Nor is it really about the heart, or love, in the traditional way thought, although love can be the final ingredient in awakening.
It is all about turning within, looking and feeling within with the intent of exploring and accepting all that one feels and perceives. Being open to oneself even while the mind is talking to you, trying to direct you according to past learning and what guru So and So said.
Instead, depending on your own self, quietly but steadfastly first look within, and then far more importantly, feel within. Feel your body, your energies, your beating heart, then emotions, depression, anger, hurt, fear, and love, desire, grace, purity, Self.
Thdn in your Heart of Hearts, the inner most chamber of the metaphorical onion that you are, you will find your Self.
