SB 10.28 Summary
A.C. Bhaktivedanta Swami Prabhupada
This chapter describes how Lord Kṛṣṇa brought Nanda Mahārāja back from the abode of Varuṇa and how the cowherd men saw Vaikuṇṭha.
The king of the cowherds, Nanda Mahārāja, observed the prescribed fast on the eleventh day of the lunar month and then considered how to break his fast properly on the twelfth day. By circumstance only a few more minutes remained, and so he decided to take his bath at the very end of the night, although astrologically that was an inauspicious time. Thus he entered the water of the Yamunā. A servant of Varuṇa, the demigod of the ocean, noticed Nanda Mahārāja entering the water at a time forbidden by scripture and took him away to the demigod's abode. In the early morning the cowherd men unsuccessfully searched for Nanda, but Lord Kṛṣṇa immediately understood the situation and went to see Varuṇa. Varuṇa worshiped Kṛṣṇa with great and variegated festivity. Afterwards he begged the Lord to forgive his servant for having foolishly arrested the king of the cowherds.
Nanda was amazed to see the influence Śrī Kṛṣṇa exerted in the court of Varuṇadeva, and after returning home he described his experiences to his friends and relatives. They all thought Kṛṣṇa must be the Supreme Personality of Godhead Himself and wanted to see His supreme abode. Thereupon the omniscient Personality of Godhead arranged for them to bathe in the same lake where Akrūra would have his vision of the Absolute Truth. There the Lord revealed to them Brahmaloka, which is realized by great sages in their mystic trance.
