What does the word offerings mean?
"He must then respectfully make offerings to the guest-monks, in accord with the Dharma" (BNS)-- Here and in a few other places, it seems to mean the same thing as dana-- donations of money or materials to monks.
"Hence, if he does not make offerings to the sutras and moral codes, in accordance with the Dharma, he commits a secondary offense." (BNS) -- Not sure what they mean here. You can't give a lunch to a sutra. This means something different than in the 1st case. Is this just rhetorical flourish that means one should read and follow the sutras and moral codes?
Also, are offerings a part of maintaining a home altar in Chinese Buddhism? What, if any thing, is typically "offered"? What does one do with the offerings afterwards (particularly the food and the like)?
