This is the grandson of Tertön Sogyal, Tromge Tulku Khacho Dechen Wangpo, a great meditator who lives in eastern Tibet. I was honored to meet him a few times and to talk about Tertön Sogyal. I once told him that I wanted to write the biography of his grandfather, and asked for his blessing to do so. He gave me a white prayer bead from his rosary for the endeavor, which I put around my neck to bless my speech, and written word!
