I asked Carl Jung whether he had anything to say about meaning in life, and flipped open my new copy of Memories, Dreams, Reflections. Here's what I read, on page 324 (I've re-translated all of the "default male" language into broader inclusive terms):
Unconscious wholeness therefore seems to me the true spiritus rector [guiding spirit] of all biological and psychic events. Here is a principle which strives for total realization — which in our case signifies the attainment of total consciousness. Attainment of consciousness is culture in the broadest sense, and self-knowledge is therefore the heart and essence of this process. The East attributes unquestionably divine significance to the self, and according to the ancient Christian view self-knowledge is the road to knowledge of god.
The decisive question for us is: are we related to something infinite or not? That is the telling question of our lives. Only if we know that the thing which truly matters is the infinite can we avoid fixing our interest upon futilities, and upon all kinds of goals which are not of real importance. Thus we demand that the world grant us recognition for qualities which we regard as personal possessions: our talent or our beauty. The more a person lays stress on false possessions, and the less sensitivity they have for what is essential, the less satisfying is their life. They feel limited because they have limited aims, and the result is envy and jealousy. If we understand and feel that here in this life we already have a link with the infinite, desires and attitudes change. In the final analysis, we count for something only because of the essential we embody, and if we do not embody that, life is wasted. In our relationships to other people, too, the crucial expression is whether an element of boundlessness is expressed in the relationship.
I don't feel much of a link with the infinite, but it sure sounds nice.
