The feeling of gratitude does not correspond to one of the basic emotions. Quite the opposite. To experience it requires a series of complex processes in the mind. Not everyone can experience gratitude. It is a virtue reserved for the highest spirits and the best developed intelligences.

Unlike other feelings, that of gratitude does not appear as an impulse simply. Gratitude requires that there be a system of ethical values, where the concepts of giving and receiving are resolved, as well as a renunciation of the egocentric vision of life.

"When gratitude is so absolute, words remain."
