Lyric discussion by eskimotaro 

I think the answers are simply...there are no answers at all.

By giving no answer, the man under the tree is saying that there are no solution. You are suffering because you are bothering yourself with those question, thus the answer is to forget all your pain and enjoy your life. "my time is brief"

If I am not wrong, that is a belief that people believe in in Buddhism. I believe this song has Buddhism reference, because of the image of a difficult pilgrim that the men goes through and how they always end up satisfied with their questions under a tree. Buddha also went through a long and difficult pilgrim and later get enlightened under a tree, he then delicated himself into aiding mankind by giving out sermons and answering questions.
