Yōga Sūtra 4.31

तदा सर्वावरणमलापेतस्य ज्ञानस्यानन्त्याज्ज्ञेयमल्पम्।

tadā sarvāvaraṇamalāpētasya jñānasyānantyājjñēyamalpam।

[तदा सर्व आवरण मल अपेतस्य ज्ञानस्य अनन्त्यात् ज्ञेयम् अल्पम्।
tadā = then; sarva = all; āvaraṇa = veils of; mala = impurities; apētasya = having dissolved; jñānasya = the knowable; anantyāt = to be infinite; jñēyam = the knowledge; alpam = as finite;]

Then, having dissolved all the veils of impurities, one understands the knowable to be infinite and (our) knowledge is finite.
