The Meaning of Yoga
Any change, in the normal behavior of the mind, can be an altered state. When we get angry, it is an altered state of consciousness; when we go to sleep, it is another altered state; and when we express ourselves, we create altered states. There are some experiences, which bring the mind down towards the gross, instinctive, and rational plane; and other experiences that go beyond the instinctive and rational level, which are probably best expressed by the term “intuitive states of mind.”
