Srimad Bhagavatam 7.9.18
so ’haṁ priyasya suhṛdaḥ paradevatāyā
līlā-kathās tava nṛsiṁha viriñca-gītāḥ
añjas titarmy anugṛṇan guṇa-vipramukto
durgāṇi te pada-yugālaya-haṁsa-saṅgaḥ
O my Lord Nṛsiṁhadeva, by engaging in Your transcendental loving service in the association of devotees who are liberated souls [haṁsas], I shall become completely uncontaminated by the association of the three modes of material nature and be able to chant the glories of Your Lordship, who are so dear to me. I shall chant Your glories, following exactly in the footsteps of Lord Brahmā and his disciplic succession. In this way I shall undoubtedly be able to cross the ocean of nescience.
