When Lao-tzu says: “All are clear, I alone am clouded,” he is expressing what I now feel in advanced old age.

Lao-tzu is the example of a man with superior insight who has seen and experienced worth and worthlessness, and who at the end of his life desires to return into his own being, into the eternal unknowable meaning.

The archetype of the old man who has seen enough is eternally true. At every level of intelligence this type appears, and its lineaments are always the same, whether it be an old peasant or a great philosopher like Lao-tzu.

This is old age, and a limitation. Yet there is so much that fills me: plants, animals, clouds, day and night, and the eternal in man.

The more uncertain I have felt about myself, the more there has grown up in me a feeling of kinship with all things.
In fact it seems to me as if that alienation which so long separated me from the world has become transferred into my own inner world, and has revealed to me an unexpected unfamiliarity with myself. ~Carl Jung; Memories, Dreams and Reflections; Page 359.
