Vibhuti

रुद्रसंहितायां सृष्टिखंडे गुणनिधिसद्गतिवर्णनं नाम अष्टादशोऽध्यायः
Gunanidhi's rescue description Chapter 18



धर्मराज उवाच |
Yama said (to his assistants)



ये त्रिपुण्ड्रधरा लोके विभूत्या सितया गणाः |
ते सर्वे परिहर्तव्या नानेतव्या कदाचन || 44 ||
Assistants, those people in the (mortal) world whitened by vibhuti (holy ash) with a tripundra should be left alone and never brought here (to Yamapur).
The next few lines say that those having sprinkled vibhuti on them, dressed like Lord Shiva, or having a rudraksha on them while having tied the hair, also should be left alone and not brought here.
