From Ocean of Dharma comes this quote from Chögyam Trungpa Rinpoche, from The Profound Treasury of Knowledge, Volume Three: The Tantric Path of Indestructible Wakefulness.
Practicing dharma is not difficult; it comes naturally. It is free from hassle, and it brings a lot of health. As you practice more and more, you find that practice begins to grow inside your bones, in the marrow. Practice becomes natural. It is just like a horse that is used to being ridden: that horse begins to like the rider rather than feeling resentful. That is why we sometimes call practice “riding the mind.”
If you find that your horse is feeling resentful, you’ll find lots of helpful advice on our How to Meditate Spotlight Page. And for more on the Profound Treasury, look for Dzogchen Ponlop’s article about it, “Guide to the Three-Yana Journey,” inside the Spring 2013 Buddhadharma magazine, mailing to subscribers now.
