Mantra 38

तद्यथा राजानं प्रयियासन्तमुग्राः प्रत्येनसः सूतग्रामण्योऽभिसमायन्ति ।एवमेवेममात्मानमन्तकाले सर्वे प्राणा अभिसमायन्ति ।यत्रैतदूर्ध्वोच्छ्वासी भवति ॥बृह. ४,३.३८ ॥

In plain words

And as when a king is about to depart, the nobles, the officers, the charioteers and the village headmen gather about him, so at the last hour all the breaths gather about this self when a man is breathing his last.
