Natrinaiyil Iruthalum Iruthal Nimithamum
நற்றினணயில் இருத்தலும் இருத்தல் நிமித்தமும்
The Tamils divided the department on the basis of land. They are Kurinji, Mullai, Marutham, Neithal, and Palai. But according to the Tamil tradition there is no private land called Balai. Kurinji and Mullai change from their nature and get the character of Palai. Silapathigaram says,
“Mullaiyum Kurinjiyum muraimaiindri thirinthu
Nalliyalbu Elanthu Nadungu thuyaruruthu
Palai enbathor padivam kollum” Kadu Kaan Kaathai (64-66)
Land discrimination is intertwined with the way people live, as well as their habitat, animals, and food. The department was the moral of their land, united with the environment. When it says Internal means its ‘Agavozhukam’, when it says external means it is ‘Puravozhukam’. The quintessential discrimination is found only in the anthologies. Based on them, first, the nucleus and the adjectives are divided.
