Todalatantra 8: Toḍalatantra, Aṣṭamaḥ paṭalaḥ

The auspicious Goddess said:
The body is the abode of thirty-five million nāḍīs;
I wish to hear of them in order; tell that to me, O Lord.

The auspicious Śiva said:
In the pores of the hairs are one and a quarter million, O beautiful one;
in the hands, mouth, and then feet, three hundred thousand nāḍīs reside.

In the belly and likewise in the anus, five hundred thousand are proclaimed;
in the heart and all the limbs, nine hundred thousand are proclaimed.

Now, on the flanks, likewise on the skin, and likewise in all joints,
one hundred thousand less eleven nāḍīs reside in the body, my dear.

Iḍā and piṅgalā, and suṣumṇā, citriṇī, as well as
the brahmanāḍī within it—these are proclaimed as the five nāḍīs.

Kuhū and Śaṅkhinī, Gāndhārī, Hastijihvikā,
Nardinī, and likewise Nidrā—the number of Rudras (eleven) are established.

These nāḍīs, O supreme ruler, arise from the suṣumṇā.
With four-two-eight-nine-five [nāḍīs] ending in the water [element],
upon what support are they situated within the lotus, O Supreme Lord?

The auspicious Śiva said:
The greatness of the yoga-lotus cannot be described by me.
In the mūlādhāra, inside the lotus, is the exceedingly radiant bīja 'laṃ'.

Inside the bindu of the bīja 'laṃ' is the charming earth-circle;
in the form of concentric rings, the seven oceans reside.

The auspicious Goddess said:
Tell me the measure of the bindu, O Mahādeva; tell me, O Lord;
speak in sequence the measure of the yoga-lotus, O Śaṅkara.

The auspicious Śiva said:
The bindu is one third of an atom, immensely vast;
within it are all the oceans, the seven continents, and the earth.

Supreme Śiva is imperishable, supremely subtle, and in the form of a bindu;
and how can the measure of this god be spoken by me?

One should meditate on the world of Brahmā, O supreme ruler, above the nāda;
Brahmā accompanied by Ḍākinī always dwells there in that very way.

The syllable 'la' is the earthly bīja, embodying Śakti, O Queen of gods;
and inside the earth-circle is the wondrous Svayambhūliṅga,

always encircled by Kuṇḍalī in three and a half coils;
she remains covering the aperture of the liṅga with her own mouth.

Because of that, the air always moves through iḍā and piṅgalā;
for the vision of the sahasrāra, she is ever awake in her essential form.

As soon as she has risen up to the sahasrāra by the path of Brahman,
at that very moment, O supreme ruler, the unfolding of breath and exhalation occurs.

Inside the filaments, within the four petals, O Queen of gods,
is Durgā of infinite forms, and Śambhu bearing infinite forms.

[The Goddess said:]
He always abides in desire through various pleasures of love;
how does Kuṇḍalī remain drawing upon the aperture of the liṅga?

Tell me, O ever-blissful one; you are omniscient, O Lord of gods.
[Śiva said:]
Inside the liṅga is a great splendor, in the form of fire, O beautiful one;

because the macrocosm would be burned by anything joined with that wind,
therefore that goddess Kuṇḍalī remains covering [the aperture] with her mouth.

Because of that, one should unite the bindu-śakti in the earthen liṅga;
having raised the bindu-śakti, the worship of the liṅga is proclaimed.
