Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 27


असेवयायं प्रकृतेर्गुणानांज्ञानेन वैराग्यविजृम्भितेन ।योगेन मय्यर्पितया च भक्त्यामां प्रत्यगात्मानमिहावरुन्धे ॥ २७ ॥


asevayāyaṁ prakṛter guṇānāṁjñānena vairāgya-vijṛmbhitenayogena mayy arpitayā ca bhaktyāmāṁ pratyag-ātmānam ihāvarundhe


Thus by not engaging in the service of the modes of material nature but by developing Kṛṣṇa consciousness, knowledge in renunciation, and by practicing yoga, in which the mind is always fixed in devotional service unto the Supreme Personality of Godhead, one achieves My association in this very life, for I am the Supreme Personality, the Absolute Truth.


When one engages in devotional service to the Lord in the nine different kinds of bhakti-yoga, as enunciated in authoritative scriptures, such as hearing (śravaṇam), chanting (kīrtanam), remembering, offering worship, praying and offering personal service — either in one of them, or two or three or all of them — he naturally has no opportunity to engage in the service of the three modes of material nature. Unless one has good engagements in spiritual service, it is not possible to get out of the attachment to material service. Those who are not devotees, therefore, are interested in so-called humanitarian or philanthropic work, such as opening a hospital or charitable institution. These are undoubtedly good works in the sense that they are pious activities, and their result is that the performer may get some opportunities for sense gratification, either in this life or in the next. Devotional service, however, is beyond the boundary of sense gratification. It is completely spiritual activity. When one engages in the spiritual activities of devotional service, naturally he does not get any opportunity to engage in sense gratificatory activities. Kṛṣṇa conscious activities are performed not blindly but with perfect understanding of knowledge and renunciation. This kind of yoga practice, in which the mind is always fixed upon the Supreme Personality of Godhead in devotion, results in liberation in this very life. The person who performs such acts gets in touch with the Supreme Personality of Godhead. Lord Caitanya therefore approved the process of hearing from realized devotees about the pastimes of the Lord. It does not matter to what category of this world the audience belongs. If one meekly and submissively hears about the activities of the Lord from a realized soul, he will be able to conquer the Supreme Personality of Godhead, who is unconquerable by any other process. Hearing or associating with devotees is the most important function for self-realization.
