The full title is Light of Fearlesss Indestructible Wisdom: The Life and Legacy of Dudjom Rinpoche by Tsewang Dongyal

Dudjom Rinpoche was head of the Nyingma lineage for many years and and did vast teachings and had a miraculous death. A few of his activities are listed below:

(1) His writings number twenty-five volumes and are among the most profound and influential in Tibetan Buddhist history. They include his own terma revelations, poetry, historical treatises, and commentaries on the terma revealed by past masters, the kama teachings, and philosophy. As an acknowledged master, teacher, and expositor of instrumental and vocal music, chanting, and lama dance, as well as of esoteric practices, such as tsa-lung, tummo, and trülkhor, he also composed works on the ritual arts and yoga.

(2) He gave the empowerments of and teachings on the Treasury of Precious Treasures (the complete collection of termas compiled by Jamgön Kongtrul Rinpoche) an unprecedented ten times, to countless thousands of people, including many great masters, khenpos, and tulkus, thus securing and strengthening this vital tradition for generations to come.

(3) He collected, compiled, and edited the complete kama teachings of the Nyingma School, many of which were scattered throughout Tibet and its environs and thus in danger of being lost. He edited the existing thirteen volumes, originally printed in the u-med (dbu med) short-hand script, and reprinted them in twenty volumes in the u-chen (dbu chen) block-type script. To these, he added thirty-eight more volumes and then published all fifty eight. He also gave empowerments and teachings on the complete kama teachings three times.
