Attachment increases desire

Attachment increases desire, without producing any satisfaction. There are two types of desire, unreasonable and reasonable. The first is an affliction founded on ignorance, but the second is not. To live, you need resources; therefore, desire for sufficient material things is appropriate. Such feelings as, "This is good; I want this. This is useful," are not afflictions. It is also desirable to achieve altruism, wisdom, and liberation. This kind of desire is suitable; indeed, all human development comes out of desire, and these aspirations do not have to be an affliction. ...when you have attachment to material things, it is best to desist from those very activities that promote more attachment. Satisfaction is helpful when it comes to material things, but not with respect to spiritual practice. Objects to which we become attached are something to be discarded, whereas spiritual progress is something to be adopted--it can be developed limitlessly, even in old age.
