Śrīmad-Bhāgavatam · Text 10.64.43
Who is speaking and story frame
ब्राह्मणार्थो ह्यपहृतो हर्तारं पातयत्यध: ।
अजानन्तमपि ह्येनं नृगं ब्राह्मणगौरिव ॥ ४३ ॥
brāhmaṇārtho hy apahṛto
hartāraṁ pātayaty adhaḥ
ajānantam api hy enaṁ
nṛgaṁ brāhmaṇa-gaur iva
When a brāhmaṇa’s property is stolen, even unknowingly, it certainly causes the person who takes it to fall down, just as the brāhmaṇa’s cow did to Nṛga.
