“The Vedanta recognizes no sin, it only recognizes error. And the greatest error, says the Vedanta, is to say that you are weak, that you are a sinner, a miserable creature, and that you have no power and you cannot do this and that.”
~ Swami Vivekananda
Your alignment with Spirit, my friend, is the source of your power. No one and nothing else is. And at every moment, via your thoughts, words and deeds, you are either moving towards that alignment or away from it. Can you see how saying that you are weak, a sinner, etc., only serves to keep you from this alignment?
The only way you can change is through your own volition. Make the decision to change your self-image and then take the steps to create that change.
But don’t think of this as a heavy burden, my friend. After all, alignment feels good.
