On the same tree man sits grieving, immersed, bewildered by his own impotence (an-îsâ). But when he sees the other lord (îsa) contented and knows his glory, then his grief passes away.

In plain words: A person sits on that same tree, sunk in sorrow and confused, feeling powerless. But when they see the other bird, the Lord, calm and content, and see his greatness, their sorrow goes away.
