This post is no more than a quick note to provide the dates of Rogza Sönam Palge (rog bza’ bsod nams dpal dge), who is known primarily as a teacher of yogic practices (tsa-lung) to Patrul Rinpoche (1808–1887) and also as one of the gurus of Orgyen Tendzin Norbu (1841–1900). As far as I’m aware, his dates have never appeared in any English-language publication. Indeed, he doesn’t even have an entry on tbrc.org
Matthieu Ricard’s Enlightened Vagabond includes a brief summary (pp. 219–220) of the major facts concerning Sönam Palge’s life, such as how he studied with the First Dodrupchen Jigme Trinle Özer (1745–1821) and later followed Do Khyentse Yeshe Dorje (1800–1866) as a Dharma companion.
