निश्वासलोपैर्निभृतैः शरीरैर्नेत्राम्बुजैरर्धनिमीलितैश्च ।आविर्भवन्तीममनस्कमुद्रामालोकयामो मुनिपुङ्गवानाम् ॥ २१ ॥
In plain words
The breath has stopped coming and going. The body sits without a tremor. The lotus-eyes rest half-closed. By these three signs we watch the amanaska-mudrā — the seal of no-mind — come into the open on the greatest of sages.
Close to the Sanskrit
By breaths that have lapsed, by bodies utterly still, and by lotus-eyes half-closed — we behold the amanaska-mudrā, the seal of the mindless state, becoming manifest in the foremost of sages.
