नादबिन्दुमयं वापि किं चन्द्रार्धनिरोधिकाः।
चक्रारूढमनच्कं वा किं वा शक्तिस्वरूपकम्॥ ४॥

Transliteration

nādabindumayaṁ vāpi kiṁ candrārdhanirodhikāḥ |
cakrārūḍhamanackaṁ vā kiṁ vā śaktisvarūpakam || 4 ||

Translation

Is it nada and bindu or can it be known by concentrating on the ascending psychic centres or the unstruck sound which emanates without any vibration? Or is it the form of the obstructing half moon or else is it the form of shakti?
