Verses 21 - 31 seem to refer to the rites of public worship of Ra-Hoor-Khuit.

With regard to the Old Comment, I did indeed find an image of the kind implied. But there seems no special importance in this. I am inclined to see some deeper significance in this passage. There has elsewhere been reference to the words "not", "one", "Thou knowest". The word "easy" is moreover suggestive of some mystery; it is used in the same doubtfully intelligible sense in verse 40.
