Boundless Vision presents the Dzogchen practices of the Tibetan Northern Treasure tradition of the master Godemchan according to the 19th century master Tulku Tsulo. Tulku Thondrup Rinpoche's translation has been edited by Keith Dowman.

Tulku Tsulo's lamrim text begins in Part One with the preliminary Dzogchen practices (ngondro) including the Five Nails, all treated at length. These elementary levels are evidently designed for newcomers to the Nyingma path. Part Two begins with the inner, Dzogchen, preliminaries (rushen) and then treats the trekcho and togal central meditations, providing clear and detailed instruction and metaphorical indication for both meditation phases. The Breakthrough (togal) section emphasizes direct introduction, while the Leap-over (togal) section, thoroughly explicates the four lamps and the four visions. Bardo descriptions as meditation experience in this life conclude this section. Part Three summarizes the result and completes the text.
