यं विज्ञातँ स्याद्वाचारम्भणं विकारो नामधेयं मृत्तिकेत्येव सत्यम् ॥ ४ ॥
In plain words
Knowing that single reality through which every modification—born of words and ending in a mere name—is understood, you know the truth: only clay is real.
Close to the Sanskrit
By knowing which, everything like the modification, which has its origin in speech and is a mere name, is known: clay alone is the truth.
