Yes, I think it makes sense. Let me give you the actual reason so you can judge it, not just take my word.

Your book already contains the glossary, 43 defined terms, fully written. So this costs you almost nothing to publish. That’s the key point: it’s not new work, it’s content you already finished.

Why it earns its place:

Nobody else on the internet uses words like Achronopneuma, Theonektar, Katasigesis. So the moment you publish them, you rank first on Google for every one, because there’s no competition. That’s rare and free.

It’s the payoff mechanism for your videos. When you say these terms in a YouTube talk, people will search them. If the glossary is public, that search lands on your site. If it’s not, it lands nowhere, or on someone else’s interpretation.

It shows depth to a stranger. A visitor skimming 43 precise, original terms immediately sees this is a serious system, not vague spiritual talk. That’s persuasion without you selling.

The honest caveat, so this isn’t a false pitch: this is branded traffic, not discovery traffic. People won’t find you by searching “Achronopneuma” cold, because they’ve never heard it. They find it after hearing you say it. So the glossary’s value is real but downstream of your videos, not a standalone traffic magnet. I said this a few turns back and it still holds.

Net: low effort, real long term payoff, no downside. That’s why I recommend it. But it is genuinely optional for launch, so if you’d rather keep the menu lean tonight and add it later, that’s also fine and costs you nothing to defer.

Your call. If yes, add one more page named Glossary and we include it. If you’d rather wait, we move on with seven. Which?
