Dissolution Threshold and the Fourteen Abodes
ब्रह्मलोकः समाख्यातो यत्र ब्रह्मा पुरोहितः / ते सर्वे प्रणवात्मानो बुद्धिशुद्धतया स्थिताः
brahmalokaḥ samākhyāto yatra brahmā purohitaḥ / te sarve praṇavātmāno buddhiśuddhatayā sthitāḥ
That realm is called Brahmaloka, where Brahmā serves as the sacred priest. All who dwell there are of the nature of Pranava (Om) and abide in purity of intellect.
