हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

HAṬHAYOGAPRADĪPIKĀ 79
92. When the mind, having discarded its restless-
ness [caused by its constant identification with sense-
objects], is held [steadfast] by Nāda, it becomes totally
immobile, like a bird that has lost its wings.
Having controlled Prāṇa by Prāṇāyāma, and the senses by
Pratyāhāra, the mind should be concentrated on the abode of all
good, God. This is Dhāraṇā.
93. One who is desirous of obtaining sovereignty
in Yoga should put away all mental activity, and, with
a fully concentrated mind, should meditate on Nāda
only.
That is, his mind becomes one with the Nāda, which represents
the stage of Dhyāna.
94. Nāda is like the net which ensnares the deer
within [i.e. the mind] and it is also the hunter who
slays the deer within [the mind].
Like the hunter, Nāda first attracts the mind and binds it,
and then kills it, i.e. it puts an end to the natural unsteadiness
of the mind and then absorbs it into itself.
95. It [Nāda] is like the bolt which locks the
horse within [i.e. the mind] of a self-controlled [Yogin].
A Yogin should therefore daily practise meditation upon
Nāda.
96. The mind is like quicksilver which, by the
action of Nāda which is like sulphur, is bound [solidified]
and freed of its restlessness, and is able [enables one]
to move in the supportless sky [which is Brahman].
