Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 47

Sanskrit:

पतित: स्खलितश्चार्त: क्षुत्त्वा वा विवशो गृणन् ।हरये नम इत्युच्चैर्मुच्यते सर्वपातकात् ॥ ४७ ॥

ITRANS:

patitaḥ skhalitaś cārtaḥkṣuttvā vā vivaśo gṛṇanharaye nama ity uccairmucyate sarva-pātakāt

Translation:

If when falling, slipping, feeling pain or sneezing one involuntarily cries out in a loud voice, “Obeisances to Lord Hari!” one will be automatically freed from all his sinful reactions.

Purport:

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura explains that Lord Śrī Caitanya is always loudly chanting the song haraye namaḥ kṛṣṇa in the courtyard of Śrīvāsa Ṭhākura and that this same Lord Caitanya will free us from our materialistic enjoying propensity if we also loudly chant the glories of the Supreme Lord Hari.
