“In Tibet these days, some instructions advise that meditation is to remain in equipoise on emptiness. Some say that meditation is to rest in the clarity of mind, and some say that meditation is to abide in bliss. There are so many different instructions on the ways to meditate. But for me, there is no more profound way to meditate than through devotion (mogu; mos gus; མོས་གུས). Yet these days there are few that believe it is possible to be liberated through the power of devotion.”
Lama Zhang Rinpoche (1122–93)
