Śrīmad-Bhāgavatam · Text 4.21.40
Who is speaking and story frame
पुमाँल्लभेतानतिवेलमात्मन:
प्रसीदतोऽत्यन्तशमं स्वत: स्वयम् ।
यन्नित्यसम्बन्धनिषेवया तत:
परं किमत्रास्ति मुखं हविर्भुजाम् ॥ ४० ॥
pumāḻ labhetānativelam ātmanaḥ
prasīdato ’tyanta-śamaṁ svataḥ svayam
yan-nitya-sambandha-niṣevayā tataḥ
paraṁ kim atrāsti mukhaṁ havir-bhujām
By regular service to the brāhmaṇas and Vaiṣṇavas, one can clear the dirt from his heart and thus enjoy supreme peace and liberation from material attachment and be satisfied. In this world there is no fruitive activity superior to serving the brāhmaṇa class, for this can bring pleasure to the demigods, for whom the many sacrifices are recommended.
