In plain words
Sound, touch, form, taste and smell: these, the qualities of the five senses, matter greatly to man. By the negative qualities of these five senses man falls into sin. He must be freed from this sin. How can he be freed? See what you should see, hear what you should hear, eat what you should eat, smell what you should smell, touch what you should touch. That is what I say from time to time:
See no evil, see what is good Hear no evil, hear what is good Talk no evil, talk what is good Do no evil, do what is good Think no evil, think what is good.
These words are very small, but all bonds are held within them.
Bondage itself is the real demon for man. He must escape from this demon, get free of constraint, and form a relationship. So the root cause of bondage and of freedom is the mind. It is the mind that desires everything. You must ask whether what it desires is an object of the senses or a poison. All objects of the senses are the same as poison. You must take care not to let this mind go out to the objects of the senses. Even if it does go, you must draw from them what is best. You smell with the nose. You want to smell only fragrance. But along with fragrance you must also draw in the vital air with the breath going in and out. You eat food to still your hunger. But you must eat this food too as food that gives health. In the same way you listen to all sorts of crazy things on TV or on the radio. This is not what you should hear; you must hear what gladdens the heart. You must hear only what gives joy to the antaḥkaraṇa.
