What were the sixteen rituals for the body that the author experienced, including the naming ceremony?

The source material from Chapter 2 mentions that "From birth to death, there are sixteen rituals for the body," but it does not provide a list or description of what these sixteen rituals are. It only specifies that the "naming ceremony" (Namakaran) is one of these well-known rituals. The author brings this concept up solely to introduce the sub-story of how he was given the name "Hemadpant." However, as Chapter 2's excerpts show, the text does not go into any detail about the other fifteen rituals, focusing instead on setting the context for the author's personal story of receiving his famous name.
