This is my own article from americanmonk.org . It talks about seniority and quotes the story from the vinaya texts about animals that were talking to each other to and discovering who was most senior. We touched on this topic before. However, the end of the story … not quoted in my article has the Bodhisatta (the bird), preaching 5 precepts to the other animals.
The article might be interesting for those who interested in the backstory of monk life. This theme was one of my original purposes for my blog before it branched into other subjects and themes.
