Purport: 

One can achieve the highest perfection of life simply by meditating upon the lotus feet of Śrī Caitanya Mahāprabhu. Generally people are concerned with the four religious principles, namely religion, material opulence, sense gratification and liberation. However, as indicated in Śrīmad-Bhāgavatam (dharmaḥ projjhita-kaitavo ’tra), success in these four kinds of material and spiritual gain are not the true results of devotional service. The true result of devotional service is the actual development of one’s dormant love for Kṛṣṇa in every circumstance. By the mercy of Śrī Caitanya Mahāprabhu, Gopīnātha Paṭṭanāyaka could understand that the material benefits he had achieved were not the ultimate result of meditating upon His lotus feet. The true result comes when one is detached from material opulences. Therefore Gopīnātha Paṭṭanāyaka prayed to the Lord for such detachment.
