[Dialogue] Do you know when we did this?

I have found a set of 16 "rituals" each based on a quote like "I am seized by people's pain, and I am shocked by the way I can't stop caring" with no named author. The ritual starts Leader - community, etc. and then quotes an Ancient Declaration and a Contemporary Declaration, then The New Decision is a list of questions to be asked, and then the Leader closes with a one line and then there is a song quoted on the bottom of the page. I am thinking this must have been a prior's council or something. Were they usually 16 days? Anybody have any ideas?
