Misinterpretation of a Pali phrase - Rupan Jirathi

Yesterday I saw in a funeral banner the following statement. > Rupam Jirati Machanam, Nama Gottam Najirathi It means, "the body decays but the Name and the Tribe does not". But I have concerns on this. The first part of the statement is valid but however the second part doesn't for me. If everything decays/dies then how is the name and tribe doesn't? For me this is clearly a misinterpretation and destroys the whole base of the Buddha's teachings. I also found this article on this topic as well: - The Common misinterpretations of a Pali Verse that states the body decays but the Name and the Tribe does not Is there any Tripitaka source to this statement? or anything similar? Where can I find it?
