Ego is the basic operating system for your mind. You must have an ego, you must have a self-awareness and you must also have an operating system that works for your karma; your social obligations for this life. You also must train your ego, because as a yogi, you realize that the ego is not you, its just the framework that your mind works in to control this body. The more words that are said, the more must be said. Words themselves create the reality because they’re sound vibrations, they create a matrix of consciousness. But beyond that matrix of consciousness is who you are. So, you must learn how to program your mind. For us we’ll use the English language for the most part. We’ll also use mantras from this culture and other cultures. A mantra is just a sound vibration that reprograms the mind.
