“Of all the devotional prayers used as a support for Dharma practice, the Seven-Line Prayer is the most essential, often repeated many thousands of times by practitioners of Tibetan Buddhism. This concise prayer invokes the blessings of Padmasambhava, also called Guru Rinpoche (“Precious Teacher”) and known as the Buddha of our time.” ~ Khaybje Thinley Norbu Rinpoche, SolePanacea
Lama Sonam Rinpoche has requested (but not required) that those who are wanting to start their Ngondro practice begin by accumulating 10,000 recitations of the 7 Line Prayer. This is very important because these recitations can remove obstacles to accomplishing Ngondro and are a way of making a deeper connection to Guru Rinpoche.
