Lama Sonam Thayé
Lama Sonam Thayé (Wyl. bla ma bsod nams mtha' yas) aka Chomden Dorje (Wyl. bcom ldan rdo rje) was one of the two main ‘heart-sons’ of Nyala Pema Düddul (1816-1872), the other being Tertön Rangrik Dorje. He passed the lineage of Nyala Pema Düddul on to Tertön Sogyal. He was renowned as an emanation of Gyalwa Chokyang, one of the twenty-five disciples of Guru Rinpoche. Born into the family of Akalbu (a skal bu), he became a yogin who dressed in white and wore his hair in a top knot. He assisted in the construction of the main temple at Kalzang Monastery and took responsibility for all Pema Düddul's disciples after their master attained the rainbow body.
