It has been said that the body is the temple of the spirit and the mind is the altar within that temple. When we practice hatha yoga, we allow ourselves to come fully into the temple of the body—not simply as a tourist wishing to admire the fine architecture, but as a seeker on a pilgrimage of deep devotion and reverence.
Meditation is the devotional practice of placing on the altar of the mind that which is sacred, holy and revered. Just as you would not place garbage on the altar of a great temple, meditation allows a yogi to place on the altar of her mind that which is noble, pure and free from attachment.
