Various doctrines throughout history have understood and expounded that the central problem of human existence is to justify it, which is only done through life itself, through acts that serve as answers. The terminologies vary, as do the recommended paths; what does not vary is the notion of the need for this individual awareness and its implications, that is, the need to act in accordance with the aspirations of one’s intimate nature. Only in this way is possible an affirmation that is worth to the human being as a universal balm. Therefore, by the most diverse means, what the great doctrines teach is the orientation of life around a purpose—and man, defining it, has the mission to strive for its fulfillment.
