Text 21

ami hi tvam sura-sangha vishanti
kecid bhitah pranjalayo grnanti
svastity uktva maharsi-siddha-sanghah
stuvanti tvam stutibhih puskalabhih

Translation

All the hosts of demigods are surrendering before You and entering into You. Some of them, very much afraid, are offering prayers with folded hands. Hosts of great sages and perfected beings, crying “All peace!” are praying to You by singing the Vedic hymns. 

Commentary by Srila Prabhupada 

The demigods in all the planetary systems feared the terrific manifestation of the universal form and its glaring effulgence and so prayed for protection.

Commentary by Sri Visvanatha Cakravarti Thakur

Tva stands for tvam.
