Morals. The book is rich  in etiquette and taboos, which are classificatory of any literature teaching morals. Etiquette. The general importance of character elements of an individual namely blessings of parents (4), respect of five elements namely "brahmins", cows, the Sun, the moon, the king and teachers (15,16, 74) and importance of speech (1) is stressed. Eating rules of eating like eating after feeding elderly, cows, birds and children (21, 26, 86) and direction of eating (24).

Caste Treatise. The notion of untouchability seems to have emerged in the Sangam period itself with references from the work indicating water touched by "pulaiyar" being considered unfit for consumption of higher caste. "Pulaiyars" are referred as meat eaters (since "pulai" means "meat"). Criticism. The presence of this work in the Sangam literature is  debated as the period of compilation is found to be in the late 8th century. There is heavy dosage of "Brahminical" influence in verses 2, 5, 15, 31, 34, 41, 47, 48, 61, 64 and 92. There is heavy influence of Sanskrit literature in the style of the work.
