Learn to be internally alone. Don’t allow people and things to invade your being.
Edward Salim Michael: Yoga and the Trinity
Hatha Yoga should, right from the start, be practiced in three directions simultaneously. That is to say, the three aspects of human nature—the mental, the emotional, and the physical—should become unites as one in this difficult struggle, all three participating equally in it.
Generally, this trinity in a human being is dissociated, but from his ordinary dispersed condition, it is not possible for him to see this. It is only when he tries to make conscious efforts to be present to himself that he begins to perceive this problem. For, each time he strives to become more aware of himself and starts to lose his ground once more, sinking back into his habitual state of being, he has a chance to understand a little better the particular aspect of his nature that has separated itself from others and is refusing to participate, stubbornly going its own way and dragging him down again into his customary state of passivity. It will show him why his endeavors in this domain fail most of the time, merely a blind groping, forced and frustrating; and also why he cannot maintain such efforts for long.
These three aspects in the human being are usually in a state of disunity, each running wildly in a different direction. The only occasion when they work together in unison to some extent are in moment of extreme danger. If a seeker wants to have a right comprehension of the inner world of mysticism and a correct vision of his True Nature, it is essential that he first clearly sees and, to a certain extent at least, puts in order this inner disunity in the house of his being.
