 According to Chelliah, this poem suggests that the 2nd-century Tamil society ate meat, and the shift to vegetarian lifestyle happened in later centuries.The god of war Murugan, a goddess possibly Kali Kankalan, along with the ceremonial ancestral offering of red rice to crows ("shraddha") are mentioned in the poem.A few lines of "Porunarattrupadai" allude to the rebirth and karma ("ool") theories, suggestive of Brahmanical ideas.
