Crystal Clear an important meditation manual on Mahamudra by Thrangu Rinpoche is a commentary to the classic meditation manual on Mahamudra meditation by Tashi Namgyal's Clarifying the Natural State. In his straightforward and lucid style Rinpoche gives us an indispensable guidebook for Tranquility or Shamatha and Insight practice (Vipashyana). For people who want more than just theory, this is a handbook that begins with watching the breath and leads practitioners through stages of realization, all the way to complete enlightenment.

“In Mahamudra, as one takes the path of direct perception, a person can obtain true and complete enlightenment within the same body and lifetime. Whatever the situation, Mahamudra provides appropriate methods and techniques. So, whether one is able to undertake a lot of hardship or not, whether one is very diligent or not, whichever type of person you might be there is always great benefit in practicing Mahamudra. The practice can be done in the solitude of retreat or while involved in the daily complexities of modern life. Mahamudra training is always applicable in any situation, at any moment of life.” -- Thrangu Rinpoche
