Ven. Khenpo Tsewang Dongyal Rinpoche requests PBC sangha members to accumulate the 100-Syllable Mantra of Vajrasattva from March 8 through the anniversary of the mahaparinirvana of Venerable Khenchen Palden Sherab Rinpoche on June 27, 2012. In this way, we will dispel all obscurations and obstacles, accumulate merit, and receive the blessings of our precious Teacher. These recitations can be included in your Ngondro accumulation.
