Commentary: In texts 121 through 128 Gopa-kumāra relates how he was convinced to go to Satyaloka. He tells how he first got an idea of the glories of Satyaloka by seeing in person that planet’s ruler, Lord Brahmā. On Puṣkara-dvīpa, within the Bhū-maṇḍala system, Lord Brahmā is worshiped as a representative of the Personality of Godhead. Gopa-kumāra, who knew nothing about Lord Brahmā’s existence, simply describes what he physically saw.
