Famous Ashvaghosha Quote
When one is rising, standing, walking, doing something, stopping, one should constantly concentrate one's mind on the act and the doing of it, not one ones' relation to the act or its character or value... One should simply practice concentration of the mind on the act itself, understanding it to be an expedient means for attaining tranquility of mind, realization, insight, and wisdom.
