You’re on the right track when conflicts of duty seem to be resolved, and deviate when decisions are made in defiance of the heart. From this the luminance of Self becomes visible, which cannot be seen any other way. The experience of Self is ever a defeat for the ego. Its all-pervading nature makes it brighter than the ego, and confronts it with dilemmas which it would prefer to avoid.
When you center yourself and cut out any other prospects, when you find a singular purpose to seeing what you aim for through to its end then you’re on the right track. When you compromise that aim because of x, y, or z then you fall away from the path that you know will lead to fulfillment.
“Sin,” the Judeo-Christian term used so commonly as a deviation from the Most High’s ordinance comes from the Greek archery term ἁμαρτία “hamartia,” meaning to miss the mark, and applies succinctly here. When you run counter to your aim, then you miss the mark of that particular aim, effectively sinning.
“Self” is God within you. The Sanskrit नमो नमः “Namo Namaha” capitalizes on this idea, and suggests a salutation to the divinity within you. That divinity is greater than the ego that makes up who you ‘think’ you are.
Experiencing that “self” defeats any notion of who you think you are, and forces you to confront problem areas in your life that you would much prefer to keep hidden away in the depths of your subconscious. What are you suppressing that keeps you away from achieving your aim?
