Khetsun Sangpo Rinbochay provides an illuminating, expansive, and practical commentary on Mi-pam-gya-tso's incisive work on the Great Completeness view of ultimate reality, called The Meaning of Fundamental Mind, Clear Light.
Mipham Gyatso, also known as Ju Mipham (1846-1912) was a great Nyingma yogi-scholar and one of the leaders of the Rime (nonsectarian) movement in eastern Tibet.
The main theme is primordial enlightenment in the basal clear light, self-arisen pristine wisdom. The emphasis is on being introduced to and identifying fundamental mind in naked experience through a lama's quintessential instructions.
The combination of topic, well-known authors, and accessible presentation of the material should make this an important book for practitioners.
