Chinese Zen Master, Disciple of Ma-tzu, T'ang Dynasty Ch'an Monk
"When you stop thinking that things have a past or future, and that they come or go, then in the whole universe there won't be a single atom that is not your own treasure. All you have to do is look into your own mind; then the marvelous reality will manifest itself at all times. Don't search for the truth with your intellect. Don't search at all. The nature of the mind is intrinsically pure."
"This so-called "perception" is one's own Nature. One's own Nature, originally pure and clean, deep and still, is, in fact, in its voidness, perception."
"If you give rise to a thought of duality, that is worldly feeling. On the other hand, if you do not give rise to a thought of duality, that is holy feeling."
"The ten vices are as follows: killing, stealing, carnality, lying, slander, coarse language, affected speech, cupidity, anger and perverse views. The ten virtues are quite simply defined as not engaging in the ten vices."
"Ma Tsu: What do you hope to gain by coming here? Hui Hai: I have come seeking the Buddha-Dharma [the way to Truth]. Ma Tsu: Instead of looking to the treasure house which is your very own, you have left home and gone wandering far away. What for?... Hui Hai: Please tell me to what you alluded when you spoke of a treasure house of my own. Ma Tsu: That which asked the question is your treasure house. It contains absolutely everything you need and lacks nothing at all. It is there for you to use freely, so why this vain search for something outside yourself?"
"The mind unmoved remaining ever serene in all conditions is Dhyana (meditation). To perceive the mind unmoved and yet to raise no thoughts as to is un-movability, to perceive the mind pure and undefiled, and yet to raise no thought as to its purity, to discriminate what is bad from what is good and yet to feel no defilement by them, and to be absolute master of oneself; this is known as prajna."
