The Sanskrit word for tsok is Ganachakra, which means wheel of accumulation. It is a gathering of yogis and yoginis that make offerings and undertake purification on a particular day according to the Tibetan lunar calendar. The great master Guru Rinpoche promised he would come to anyone who prayed to him on the 10th of the Tibetan calendar. At Yeshe Nyingpo on Guru Rinpoche we do the Heart Essence of the Lake Born tsok (Tsokse Thuk Tig) revealed by Dudjom Rinpoche. According to Shenphen Dawa Rinpoche doing tsok is the swiftest way to purify obstacles and accumulate merit. Please arrive early and bring food and drink to offer for the ritual feast.
