SB 3.18.13, Translation and Purport

Sri Maitreya said: The demon, being thus challenged by the Personality of Godhead, became angry and agitated, and he trembled in anger like a challenged cobra.

A cobra is very fierce before ordinary persons, but before an enchanter who can play with him, he is a plaything. Similarly, a demon may be very powerful in his own domain, but before the Lord he is insignificant. The demon Rāvaṇa was a fierce figure before the demigods, but when he was before Lord Rāmacandra he trembled and prayed to his deity, Lord Śiva, but to no avail.
