The ancient sages grappled with that feeling too, and they left us some pretty intense imagery to describe it.

Ecclesiastes, or Kohelet as it's known in Hebrew, is a book all about this kind of existential pondering. It's full of phrases like "vanity of vanities, all is vanity!" It’s a real party starter, right? But within that apparent bleakness, there's a lot of wisdom, if you know where to look.

One striking interpretation comes from Kohelet Rabbah, a collection of rabbinic commentary on Ecclesiastes. When Kohelet says, "I returned and saw vanity under the heavens," (Ecclesiastes 4:7) Kohelet Rabbah takes it to a rather… dramatic place. It declares that this phrase, this very sentiment, is actually the banner of the Angel of Death.

Whoa.

Let's unpack that. Why the Angel of Death? What does it even mean to say that "vanity" is this angel's banner?

Think about what a banner represents. It's a symbol, a rallying cry, a visual representation of power and authority. So, if "vanity" is the Angel of Death's banner, it suggests that the fleeting, ultimately meaningless nature of earthly pursuits is the very force that gives death its power. It's the emptiness, the lack of lasting substance, that makes mortality so poignant.

It's a bleak thought, sure. But maybe, just maybe, it's also a wake-up call.

If the Angel of Death's power comes from our obsession with things that don't last, doesn't it stand to reason that we can diminish that power by focusing on what does? On things like connection, meaning, and acts of loving-kindness – things that transcend the fleeting nature of earthly existence.

Perhaps Kohelet Rabbah isn't trying to scare us. Maybe it's trying to shake us out of our complacency. To remind us that life is short, and that we have a choice: We can chase after the wind, or we can build something that truly endures. What will our banner be?
