A devotee should always aspire to live in the association of advanced devotees and engage in the service of the Lord through the paramparā system. One should serve the mission of Śrī Caitanya Mahāprabhu through the instructions of the great Gosvāmīs of Vṛndāvana. This is called tāṅdera caraṇa sevi.
While serving the lotus feet of the Gosvāmīs, one should live in the association of devotees (bhakta-sane vāsa). This is the business of a devotee. A devotee should not aspire for material profit or lament for material loss. When Aṅgirā Ṛṣi and Nārada saw that Mahārāja Citraketu, an advanced devotee, had fallen in the darkness of ignorance and was lamenting for the material body of his son, by their causeless mercy they came to advise him so that he could be saved from this ignorance.
