I don't see myself necessarily bound by my obligation on this on (obligations vary, but i think to explain all is not within the spirit of them ). Certainly our GL works with a fairly open approach. Here, the general consensus is you are correct, 'ritual' is not secret.
That said, masonry calls you to be courteous. To start a conversation around this would make my brothers on posts above uncomfortable, and i am not going to do that without a decent reason. There will be no profit or pleasure in it, even for the questioner who should discover rather than be told these lessons...
Even if those posts were not there, i probably would not get into this. Freemasonry is a progressive, (initially at least) linear , subjective and a journey. You're asking about the final degree journey in the craft, without the context or understanding of those prior. Trying to unpack that box before you've opened the first two would sell short those presents and the craft in particular.
If you are qualified, begin the journey with faith.
