However, many people may not realize that during the last few years of his life Maslow believed self-transcendence, not self-actualization, was the pinnacle of human needs. What's more, it's difficult to find any evidence that* he ever actually represented his theory as a pyramid*. On the contrary, it's clear from his writings that he did not view his hierarchy of needs like a video game-- as though you reach one level and then unlock the next level, never again returning to the "lower" levels. He made it quite clear that we are always going back and forth in the hierarchy, and we can target multiple needs at the same time.
