“Each ray of light from the body of a buddha is able to mature and liberate immeasurable sentient beings. Buddhas emanate bodies that appear before each sentient being. These forms are tailored to the mental dispositions, sense faculties, wishes, and karmic tendencies of these beings. Buddhas can teach them the Dharma in their individual languages. These are some of the capabilities of buddhas.”
