Pleasure and pain arise from a cause, as we all know. Whether certain consequences are due to a single cause or to a group of causes is determined by the nature of those consequences. In some cases, even if the cause factors are neither powerful nor numerous, it is still possible for the effect factors to occur. Whatever the quality of the result factors, whether they are good or bad, their magnitude and intensity directly correspond to the quantity and strength of the cause factors. Therefore, for success in avoiding unwished – for pains and in acquiring desired pleasures, which is in itself no small matter, the relinquishment of a great number of collective cause factors is required.

In analyzing the nature and state of happiness, it will he apparent that it has two aspects. One is immediate joy (temporary); the other is future joy (ultimate). Temporary pleasures comprise the comforts and enjoyments which people crave, such as good dwellings, lovely furniture, delicious food, good company, pleasant conversation and so on. In other words, temporary pleasures are what man enjoys in this life. The question as to whether the enjoyment of these pleasures and satisfactions derives purely from external factors needs to be examined in the light of clear logic. If external factors were alone responsible for giving rise to such pleasures a person would be happy when these were present and, conversely, unhappy in their absence. However, this is not so. For, even in the absence of external conditions leading to pleasure, a man can still be happy and at peace. This demonstrates that external factors are not alone responsible for stimulating man's happiness. Were it true that external factors were solely responsible for, or that they wholly conditioned the arising of, pleasure and happiness, a person possessing an abundance of these factors would have illimitable joy, which is by no means always so. It is true that these external factors do make partial contribution to the creation of pleasure in a man's lifetime.
