Narapatijayacarya 3.1.98

from women: whether the fruit is auspicious or inauspicious, the wise man should declare.

Now, the praise of sound.

More secret than the secret, the essence, not to be revealed, has been revealed.
This knowledge of svarodaya is situated upon the heads of the wise.

More subtle than the subtle, [this] knowledge is easily understood, producing true conviction,
a wonder in an unbelieving world, a foundation among believing people.

To the wicked and the evil, the petty, the untruthful, the defiler of the guru's bed,
to the base in nature, to the ill-behaved, the knowledge of sound is not to be given.

To the peaceful, pure, well-behaved, whose sole mind is devoted to the guru,
firm-minded and grateful, this svarodaya is to be given.

Now, the movement of the breath (haṃsacāra).

Now I shall declare another svarodaya situated in the body,
in the nature of the movement of the breath, by which knowledge born of the three times [is attained].

Kuṇḍalinī is the great power (mahāśakti), situated in the navel, having the form of a serpent.
From it ten subtle channels go upward, and from it ten go downward.

Two subtle channels go transversely in each direction, numbering twenty-four;
these become the root passages of the great power Kuṇḍalinī.

From them, fine-mouthed subtle channels, which nourish the body exceedingly,
arise to the number of seven hundred plus seven.

The primary subtle channels, however, are ten, carrying the ten vital airs.
I will speak of the names of the subtle channels and of the winds.
