As long as the living being, under illusion, accepts the body or the mind as the soul, he will always be unhappy, like a man in the burning heat of autumn. But when the same living being becomes a devotee of Lord Śrī Kṛṣṇa, the Personality of Godhead, he at once lives a soothing life, as if under the cooling rays of the moon in autumn. Lord Śrī Kṛṣṇa is so merciful that He descends to reclaim suffering humanity and preaches Bhagavad-gītā with the intense desire that all living beings give up all of their engagements and take shelter of His lotus feet. This is the most confidential part of all revealed scripture.
The example of the damsels of Vrajabhūmi Vṛndāvana (the gopīs) is given here because these eternal consorts of the Lord terribly suffered the separation of Lord Kṛṣṇa when the Lord was absent from their presence for His engagement in tending the cows in the forest. During the absence of Kṛṣṇa, the entire day would appear to the gopīs to be as unbearable as a hot day in autumn. The Lord so much appreciated this natural feeling of the gopīs that He declared His inability to repay their intense love. Lord Caitanya recommended the feeling of the gopīs as the highest mode of worship that can be rendered to the Lord. The conclusion is that the regular practice of bhakti-yoga will lead the devotee to the plane of intense love for the Lord, and that is the single qualification by which the conditioned soul is allowed to reenter the eternal life of bliss in the kingdom of God. The threefold miseries of material existence are at once nullified by intense love of God, which is the ultimate goal of cultivating the human spirit.
