Jikme Losal Özer
Jikme Losal Özer (Tib. འཇིགས་མེད་བློ་གསལ་འོད་ཟེར, Wyl. 'jigs med blo gsal 'od zer) was a direct student of Jikme Lingpa and seems to have been from Dzogchen Monastery. His name is mentioned several times in the autobiography of Jikme Lingpa and in the colophons of some of Jikme Lingpa's works.
Jikme Lingpa also wrote a piece of advice specifically for him, called 'Advice for my child Jikme Losal' (bu 'jigs med blo gsal la gdams pa). He also seems to have served as envoy between Jikme Lingpa and the kingdom of Derge.
On several occasions however, Jikme Lingpa seems to refer to 'the two Jikme Losal's', and there is another figure called Jikme Losalchen ( 'jigs med bla gsal can).
A Jikme Losal is referred to as a personal student of Jikme Lingpa in Do Khyentse's biography (Dodrupchen, 1974, page 233).
At the occasion of the printing of the Longchen Nyingtik, Jikme Losal Özer wrote a short text in 1802 that conveys a history of the Dzogchen tradition and an overview of the contents of the Longchen Nyingtik called An Ornament of Illuminating Sunlight: An Overview of the Content of the Heart Essence of the Vast Expanse (klong chen snying thig gzhugs byang rab gsal nyi 'od rnam par snang ba'i rgyan). The text was written in the royal monastery of Derge, Pal Lhündrub Teng (dpal lhun grub steng).
