You might wish to start with the Introductory course: Training the Mind: An Introduction. In this short home study course, Phakchok Rinpoche discusses the importance of the mind–and how to go about transforming it. The course includes video teachings, written summaries, and reflection questions. It is a great introduction for those who are curious about Buddhist meditation, but is also a wonderful review for people who need more inspiration for their meditation practice.
Samye Institute also offers a home study course on a classic Mahāyāna sūtra, The Noble Wisdom of the Time of Death. This course features 8 video teachings by Phakchok Rinpoche on this important text as well as two classical commentaries on the text. We thus learn how to practice meditation by first hearing, reading, and contemplating. In this way, you can engage with the teachings and repeatedly reflect on the meaning in depth.
In addition to these short courses, Samye offers a full year program in Mahāmudrā meditation. This is called The Path of Meditation Home Practice Program. In this program, you can find a complete program of meditation instruction and a wide variety of support material.
