Veenhoven in his analysis of the "greatest happiness principle" explains that there are four types of satisfaction. Passing satisfactions are called pleasures. These are things that happen at a given point in time. They can be sensoric. For example, one may see a rainbow and it changes how they were previously feeling. Part-satisfactions relate to a certain aspect of one's life. So, a person could be happy with their personal life, but not with their career. Top-experiences are passing, but the memory of them is so profound that they stay with you over time. Religious writings often describe this type of happiness in terms of mystic moments or a state of enlightenment. Finally, life satisfaction can be used to describe one's overall state of happiness, or the summary of "pleasures and pains."
I was lucky to have the pleasure of seeing a rainbow this afternoon from my porch.
