CHĀNDOGYA UPANISHAD · 5.10.10

अथ ह य एतान् एवं पञ्चाग्नीन् वेद न सह तैर् अप्य् आचरन् पाप्मना लिप्यते ।
शुद्धः पूतः पुण्यलोको भवति य एवं वेद य एवं वेद ॥

atha ha ya etān evaṃ pañcāgnīn veda na saha tair apy ācaran pāpmanā lipyate ।
śuddhaḥ pūtaḥ puṇyaloko bhavati ya evaṃ veda ya evaṃ veda ॥

'But he who thus knows the five fires is not defiled by sin even though he associates with them. He who knows this, is pure, clean, and obtains the world of the blessed, yea, he obtains the world of the blessed.'

F. Max Müller · The Upanishads, Sacred Books of the East 1 (1879)
