65. Now, I begin to describe the practice of
devotion to Nāda (anāhata or unstruck sound) that has
been taught by Gorakṣanātha, which is suitable even
to the unlearned, who are unable [directly] to compre-

66. The primeval Lord (Śiva) has expounded
one crore and a quarter of effective ways for the
attainment of laya; but we think that the one thing,
devotion to Nāda alone, is the most important of the
[ways to] laya.
67. The Yogin sitting in the Muktāsana posture
and assuming the Śāmbhavī-mudrā, should listen with
concentrated mind to the sound within, heard in the
right ear.
These sounds proceed from the Suṣumnā. The Tripurāsāra-
samuccaya says that they are in all of ten sorts: buzzing sound like
that of a swarm of bees, sound like that of a flute, of bells, of ocean
waves, of thunder, etc.
68. Close the ears, both the eyes, the nose and
the mouth; then a clear and distinct sound is heard in
the pure Suṣumnā passage.
The ears are to be closed with the thumbs of both the hands,
the eyes with the forefingers, the nose with the middle and ring
fingers, and the mouth with the rest. This is called the Parāṅ-
mukhī-mudrā.
69. In all the Yogic practices there are four
stages: Ārambha, Ghaṭa, Paricaya and Niṣpatti.
