Śrīmad-Bhāgavatam · Text 11.18.16
Who is speaking and story frame
दृष्टिपूतं न्यसेत् पादं वस्त्रपूतं पिबेज्जलम् ।
सत्यपूतां वदेद् वाचं मन:पूतं समाचरेत् ॥ १६ ॥
dṛṣṭi-pūtaṁ nyaset pādaṁ
vastra-pūtaṁ pibej jalam
satya-pūtāṁ vaded vācaṁ
manaḥ-pūtaṁ samācaret
A saintly person should step or place his foot on the ground only after verifying with his eyes that there are no living creatures, such as insects, who might be injured by his foot. He should drink water only after filtering it through a portion of his cloth, and he should speak only words that possess the purity of truth. Similarly, he should perform only those activities his mind has carefully ascertained to be pure.
