I am a participant from the website "next door" (dhammawheel.com). I am mostly here to look, listen, and learn, but I may ask a question from time to time.
I admire the wisdom and compassion of more Mahayana teachers than I can count, but among them are Shabkar, Shantideva, Jamgon Kongtrul the Great, Yin Shun Dao Shi (whose book The Way to Buddhahood
I have recently begun to study), Je Tsong Khapa, Chatral Rinpoche, Robert Thurman, Ani Choying Dolma, and His Holiness the Dalai Lama.
EDIT: I corrected "I am from the website 'next door,'" to "I am a participant from the website 'next door.'"
