Singing the mantra of Yeshé Tsogyel

"Singing the mantra of Yeshé Tsogyel is a sem’dzin practice. One is finding presence of awareness in the dimension of sound; it is a meditative practice. The function is that the tune itself has a particular quality that enables one to enter into the state of awareness."
