Ini onnara udukkunna reethi vivarikkam. Eluppamulla reethi ethanu:
Onnaramundu arayil chutti madipolulla bhagam valichuneetti Purathekkidunnu ( Valare neelamulla madi venam ennartham. Madiyude neelam, purakil konduchennu kutthanulla athrayum venam.) . Ennittu, madi kalukalkkidayiloode pinnilekkeduthu, kundichaliloode valichu murukki purakil nithambathinte madhya bhagathu chalinu mukalilayi murukki kuthunnu. Ithu thekkan reethi aanu. Avide ethinu thattudukkalennum, kuthiyudukkalennum parayum. Neelan chutty thortho, veethi kuranja mallu murichedutha onnaramundo, karayulla kaithari onnarayo, kozhivalan thortho, thekkulla pennungal ethinupayogikkunnu.
