Never take the words that pass your mind, however ugly they are as reality; they appear from subconscious and if you are mindful just watch them as passing clouds and don’t resist or judge and energize them. They surface only to be burned in the light of your awareness. You are shuddha buddha nitya, the pure luminous Self ever uncontaminated. By ugly, I mean any thought or thoughts that rob and ruin the peace and bliss of your mind.
