Luminous is the Mind
Luminous is the mind, brightly shining, but it is colored by the attachments that visit it. This unlearned people do not really understand, and so do not cultivate the mind.
Luminous is the mind, brightly shining, and it is free of the attachments that visit it. This the noble follower of the way really understands; so for them there is cultivation of the mind.
— from the Anguttara Nikaya, translated by Gil Fronsdal
