{3} A tree may present an antidote to personal {e.g. intellectual or moralistic} lopsidedness. Just as the tree can reach high in the sky only because it is strongly rooted in the earth, so it may be that spirituality cannot be arrived at except via sensuality, and that the full development of consciousness requires the assistance of the unconscious.

{4} A withered tree may symbolize the dried-up state of, for example, a person who has lived too much in the head, with doctrines and rigid rules taking the place of instinct {intuitiveness} and the natural power of growth.
