Highlights from Nampil̤l̤ai's Vyākhyānam as Documented by Vadakkuth Thiruvīdhip Pil̤l̤ai
This incident is narrated in Śrī Rāmāyaṇam Uttara Kāṇḍam, where Viṣṇu eradicates numerous demons in Laṅkā, long before the birth of Rāvaṇa:
Aliyaik kāṇ pariyāy - Comparable to a horse that glimpses a Yāzhi.
Ari kāṇ nariyāy - Similar to a jackal that sights a lion.
