Manava Dharmashastra 6.69

6.69

jantūn kṣudrajantūniti draṣṭavyam | teṣāṃ hiṃsāyā yatpāpaṃ tadviśuddhyarthamiti sambandhaḥ |

By day and by night, if the Renunciate unintentionally injures some living creatures, he shall, for the purpose of expiating it, bathe and then perform six ‘breath-suspensions.’—(69)

Medhātithi’s commentary (manubhāṣya):
‘Living creatures’—here, should be understood as standing for minute animalcules; ‘for the expiation of the sin accruing from the injuring of these’;—such is the construction of the passage.—(69)
