Srimad Bhagavatham 11:12:1, 11:12:2
नो रोधयति मां योगो न साङ्ख्यं धर्म एव च
न स्वाध्यायस् तपस् त्यागो नेष्टा-पूर्तं न दक्षिणा
व्रतानि यज्ञश् छन्दांसि तीर्थानि नियमा यमाः
यथावरुन्धे सत्-सङ्गः सर्व-सङ्गापहो हि माम्
In his final message to Uddhava, Sri Krishna declares - "No yoga, virtuous deeds, study of scriptures, vows, vedic rituals, pilgrimages, social services to the poor and the needy, or spiritual discipline will ever as easily take us to the Lord as Satsanga can. Satsanga is the easiest way to get rid of one's attachment to the world.''
