Nanda Mahārāja, the foster father of Lord Kṛṣṇa, went to take his bath in the river Yamunā in the dead of night, mistakenly thinking that the night was already over; thus the demigod Varuṇa took him to the Varuṇa planet just to have a look at the Personality of Godhead Lord Kṛṣṇa, who appeared there to release His father. Actually there was no arrest of Nanda Mahārāja by Varuṇa because the inhabitants of Vṛndāvana were always engaged in thinking of Kṛṣṇa, in constant meditation on the Personality of Godhead in a particular form of samādhi, or trance of bhakti-yoga. They had no fear of the miseries of material existence. In the Bhagavad-gītā it is confirmed that to be in association with the Supreme Personality of Godhead by full surrender in transcendental love frees one from the miseries inflicted by the laws of material nature. Here it is clearly mentioned that the inhabitants of Vṛndāvana were extensively busy in the hard labor of their day’s work, and due to the day’s hard labor they were engaged in sound sleep at night. So practically they had very little time to devote to meditation or to the other paraphernalia of spiritual activities. But factually they were engaged in the highest spiritual activities only. Everything done by them was spiritualized because everything was dovetailed in their relationship with Lord Śrī Kṛṣṇa. The central point of activities was Kṛṣṇa, and as such, the so-called activities in the material world were saturated with spiritual potency. That is the advantage of the way of bhakti-yoga. One should discharge one’s duty on Lord Kṛṣṇa’s behalf, and all one’s actions will be saturated with Kṛṣṇa thought, the highest pattern of trance in spiritual realization.
