NOTE. This observation about Lord Rāma’s beauty is an objective one. Both the divine and the demoniac objectively acknowledge the superexcellent beauty of the Supreme Personality of Godhead when they get an opportunity to observe Him. But the demoniac still try to attack Him, as we will notice in this portion of the Rāmāyaṇa, due to their hatred towards Him.

A similar phenomenon occurred when the mighty serpent Kāliya poisoned the Yamunā. Lord Kṛṣṇa decided to teach this envious snake a good lesson and so He jumped into the river to confront him. Prabhupāda describes what took place next in the Kṛṣṇa book:

When Kṛṣṇa was swimming about just like a great strong elephant, He made a tumultuous sound, which the great black serpent Kāliya could hear. The tumult was intolerable for him, and he could understand that this was an attempt to attack his home. Therefore he immediately came before Kṛṣṇa. Kāliya saw that Kṛṣṇa was indeed worth seeing because His body was so beautiful and delicate; its color resembled that of a cloud, and His feet resembled lotus flowers. He was decorated with Śrīvatsa, jewels and yellow garments. He was smiling with a beautiful face and was playing in the river Yamunā with great strength. But in spite of Kṛṣṇa’s beautiful features, Kāliya felt great anger within his heart, and thus he grabbed Kṛṣṇa with his mighty coils. (Chapter 16)
