Who can help me explain Tagore's "Birds": "The woodcutter's axe asks for the handle from the tree. This tree is for him. " The deep meaning of? Thank you~

After reading the explanations of several people upstairs, I am worried that the meaning of this sentence will be misunderstood:

The woodcutter's axe asked the tree for its handle. This tree is for him. Such a short poem is so free and easy to express. The woodcutter needs wood as an axe to chop wood, make a living and support his family. Even if he is really needed, he will give himself generously. It can be seen that the author expresses a great kindness and tolerance. Think about it. When your best friend needs you to make sacrifices, when your relatives need you to make sacrifices, when a real child needs you to make sacrifices, or when a stranger needs your help badly, you will sacrifice yourself like a tree for free, right?

Tagore's poems express the grandeur of life in a tiny place, which is accomplished by love. etc ......
