The wild goose goes gradually draws near the tree.

Perhaps it will find a flat branch. No blame.

A tree is not a suitable place for a wild goose. But if it is clever, it will find a flat branch on which it can get a footing. A man's life too, in the course of its development, often brings him into inappropriate situations, in which he finds it difficult to hold his own without danger. Then it is important to be sensible and yielding. This enables him to discover a safe place in which life can go on, although he may be surrounded by danger.
