In the final stanza of his salutation, Tsong-kha-pa (1: 34) calls upon readers who may benefit from this approach, asking them to listen well. Such readers will be those with minds unclouded by biased thinking, the mental capacity to distinguish right from wrong, and an interest in finding real meaning in their human existence of leisure and opportunity. He asks those of us with such good fortune, “Please listen to what I have to say with a single-pointed mind.”
Again, this is strikingly similar to Aryadeva’s Four Hundred, which says that a practitioner of the Dharma who is listening to the teachings needs three qualities: objectivity, critical intelligence, and a real interest in what is being taught.
