अज्ञानकलुषं जीवं ज्ञानाभ्यासाद्विनिर्मलम् ।कृत्वा ज्ञानं स्वयं नश्येज्जलं कतकरेणुवत् ॥ ५ ॥
In plain words
The jīva is clouded with ignorance. Practice of knowledge makes it utterly clear — and then that knowledge vanishes on its own, the way kataka powder vanishes into the water it has cleared.
Close to the Sanskrit
Having made the jīva, turbid with ignorance, wholly stainless through the practice of knowledge, knowledge itself perishes — like the kataka-nut powder, having made the water clear.
