From Chögyam Trungpa Rinpoche

Openness/awareness is a state of not manufacturing anything; it is just being. There is a misunderstanding that awareness is enormous effort—as if you were trying to become an unusual species of animal. You think now you’re known as a meditator, so you should proceed in a special way to become a full-fledged meditator. That is the wrong attitude. One doesn’t try to hold oneself in the state of meditation, the state of awareness. One doesn’t try painfully to stick to it.
