Jikme Lingpa (Tib. འཇིགས་མེད་གླིང་པ་, Wyl. 'jigs med gling pa) (1730-1798) is regarded as one of the most important figures in the Nyingma lineage. Also known as ‘Khyentse Özer’, ‘Rays of Compassion and Wisdom’, he was a great scholar and visionary, and discovered the Longchen Nyingtik cycle of teachings and practice through a series of visions from the great fourteenth century master, Longchenpa. With the patronage of the Dergé royal family, Jikme Lingpa published the compilation of Nyingma tantras known as the Nyingma Gyübum and composed a catalogue to accompany it.
Revelation of the Longchen Nyingtik
Jikme Lingpa discovered the Longchen Nyingtik teachings as mind ter at the age of twenty-eight. Tulku Thondup writes:
- In the evening of the twenty-fifth day of the tenth month of the Fire Ox year of the thirteenth Rabjung cycle (1757), Jikme Lingpa went to bed with an unbearable devotion to Guru Rinpoche in his heart; a stream of tears of sadness continuously wet his face because he was not in Guru Rinpoche’s presence, and unceasing words of prayers kept singing in his breath.
- He remained in the depths of that meditation experience of clear luminosity for a long time. While being absorbed in that luminous clarity, he experienced flying a long distance through the sky while riding a white lion. He finally reached a circular path, which he thought to be the circumambulation path of Jarung Khashor, now known as Boudhanath Stupa, an important Buddhist monument of giant structure in Nepal. 
In this vision, the wisdom dakinis gave Jikme Lingpa a casket containing five yellow scrolls and seven crystal beads. One of the scrolls contained the prophetic guide of Longchen Nyingtik, called Nechang Thukkyi Drombu. At the instruction of a dakini, he ate the yellow scrolls and crystal beads, and all the words and meaning of the Longchen Nyingtik terma were awakened in his mind.
Jikme Lingpa kept this terma secret for years, and he did not even transcribe the terma until he entered another retreat in which he had a series of visions of Longchen Rabjam. Tulku Thondup explains:
- In the earth-hare year (1759) he started another three-year retreat, at Chimpu near Samye monastery. During that retreat, because he was inspired by three successive pure visions of Longchen Rabjam, and he was urged by repeated requests of dakinis, he transcribed his terma as the cycle of Longchen Nyingtik. On the tenth day of the sixth month (monkey month) of the monkey year (1764) he made his terma public for the first time by conferring the transmission of empowerment and the instructions upon fifteen disciples. 
He composed many original texts of which the Treasury of Precious Qualities (Yönten Dzö) is the most well known. His collected writings fill some fourteen volumes in the Adzom Chögar edition and nine volumes in the set produced in Dergé.
