Remembering that everything is transitory can give aid to the sorrowful mind and wisdom to the joyfully unwise one.
Even the highest of pleasures, Godhood, doesn't last. Ask Brahma.
So, breathe. Deeply, slowly. All will pass
.
Brahma, like all Gods in the God Realm, assumes much of his position.
You know, the typical: "I made everything, everything is mine, I know all"
kind of assumptions. Mara is there too, as usual.
Buddha showed Brahma how wrong he is/was.
