The monks go to dBra khyung hermitage for a one-month summer retreat every year during which they receive teachings and learn to play ritual instruments. In winter, since Klu ’bum and La kha are connected as “mother and son monasteries” (ma dgon bu dgon) they have a common winter retreat (in the 9th month). The monasteries host the retreat in turn. From the 20th to the 30th day of the same month, they perform a ritual with ’cham dance based on the sKu gsum phur sgrub, a gter ma text of gSang sngags gling pa as well as rituals of the cycle of gDugs dkar and the ceremony of the smyong gnas fasting.
