Mahamudra thoughts are an ancient method of working on the clearing out the inner channels and chakras from the inside. The purpose of all mahamudra is to see emptiness, or ultimate reality, directly. When we do see emptiness directly, all of our inner winds or prana are concentrated in the central channel of our inner body. Since the inner winds and our thoughts are linked together like a horse and its rider, we can bring the winds to the central channel if we bring the thoughts there: wherever the rider decides to lead, then the horse must follow. Later we will work from the outside, to bring the wind-horse to the central channel, which will also help the rider arrive there.
