संस्तुन्वतो निपतितान् श्रमणानृषींश्च शक्रं च वृत्रवधतस्तमसि प्रविष्टम् । देवस्त्रियोऽसुरगृहे पिहिता अनाथा जघ्नेऽसुरेन्द्रमभयाय सतां नृसिंहे ॥ १९ ॥
saṁstunvato nipatitān śramaṇān ṛṣīṁś ca śakraṁ ca vṛtra-vadhatas tamasi praviṣṭam deva-striyo ’sura-gṛhe pihitā anāthā jaghne ’surendram abhayāya satāṁ nṛsiṁhe
主也曾救度名为瓦拉奇利亚的微小苦行圣者：他们坠入牛蹄印中的水洼时，因陀罗竟嘲笑他们。随后，因陀罗因诛杀弗利特拉苏罗而招致罪业反应，被黑暗笼罩，主又护持了他。当天神之妻被困于阿修罗宫中、无依无靠时，主亦解救她们。并且主以人狮身（那罗辛哈）示现，为使圣洁奉主者无惧，诛杀了阿修罗王希兰尼亚卡西普。
