We are always in a state of anxiety and eagerness to find the first opportunity to release the tensions. It is true that desires have to be fulfilled, and unless they are fulfilled there cannot be release of tension. This cycle is the wheel of Samsara. By contact with things, desires are not fulfilled. On the other hand, desires are ignited, as it were, into a state of conflageration by such contact.
Desires arise on account of an ignorance of the structure of things.
Unless this ignorance is removed, the tension is not going to be released. The ignorance in the form of the notion that multiplicity is a reality, and that by an aggregate of all the finite things constituting the multiplicity, we can have the infinite satisfaction that we long for. A total of the finites is not the infinite, and therefore contact with finite things cannot bring infinite satisfaction. We want perpetual existence. We do not want to die.
