Yoga is a method to come to a nondreaming mind.

"So what is a good meditator? A good meditator meditates."

"Vibrate higher daily."

"A positive attitude is most easily arrived at through a deliberate and rational analysis of what's required to manifest unwavering positive thought patterns. First, reflect on the actual, present condition of your mind. In other words, is the mind positive or not? We've all met individuals who perceive themselves as positive people but don't appear as such. Since the mind is both invisible and intangible, it's therefore easier to see the accurate characteristics of the mind through a person's words, deeds, and posture. For example, if we say, "It's absolutely freezing today! I'll probably catch a cold before the end of the day!" then our words expose a negative attitude. But if we say, "The temperature is very cold" (a simple statement of fact), then our expressions, and therefore attitude, are not negative. Sustaining an alert state in which self-awareness becomes possible gives us a chance to discover the origins of negativity. In doing so, we also have an opportunity to arrive at a state of positiveness, so that our words and deeds are also positive, making others feel comfortable, cheerful, and inspired." ― H.E. Davey
"By means of personal experimentation and observation, we can discover certain simple and universal truths. The mind moves the body, and the body follows the mind. Logically then, negative thought patterns harm not only the mind but also the body. What we actually do builds up to affect the subconscious mind and in turn affects the conscious mind and all reactions." ― H.E. Davey, Japanese Yoga: The Way of Dynamic Meditation

Fear. I hadn't even known it was there." ― Claire Dederer, Poser: My Life in Twenty-three Yoga Poses

"Teaching yoga itself is great karma yoga, because it reconnects people to the source."

What wonder will I accomplish today?

Yoga is the cessation of the movements of the mind.
