Self-remembrance is a very powerful process to achieve the ultimate consciousness. Constantly in you, for a moment you remember you exist, and after a moment you will forget you exist, and your mind starts wandering here and there.
Please understand, what you do whole day using your individual identity does not matter, but where you park your individual identity when you are not doing anything really matters!
Take up any mantra to chant as ajapa japa. Develop feeling connection to any God, any guru, is okay. Unclutching from all the mortal, feeling connection strongly with immortal. This is the essence of my teachings.
You are afraid of being without thoughts. Even if you are without thoughts for a few moments, the Consciousness will conquer you, the Consciousness will capture you. Your mind will be replaced by consciousness.
