हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

HAṬHAYOGAPRADĪPIKĀ 77 79. There are the mere Haṭha-yogin-s without the knowledge of Rāja-yoga. I regard them to be practitioners who do not obtain the fruit of their efforts. 80. Contemplation on [the space between] the eyebrows, in my view, leads to the attainment of the Unmanī-avasthā in a short time. Even for people of modest intellect this is a suitable means for attaining the state of Rāja-yoga. The state of absorption arising from Nāda gives immediate experience. The results, being soon perceptible, are very convincing. 81. In the hearts of great Yogin-s who remain in a state of Samādhi through concentration on Nāda, there is a plenitude of Bliss, unequalled, surpassing all description, and which the blessed Teacher (Śrī Guru- nātha) alone knows. 82. The contemplative man (muni), having closed his ears with the [thumbs of the] hands, should focus his mind on the [mystical] sound [that is heard within] until he attains the immutable (Turya). 83. Through the process of sustained listening, this inner sound drowns the external sounds. The Yogin [who devotes himself to the Nāda] overcomes all instability of mind in fifteen days, and becomes happy. 84. During the initial stages of the practice, various prominent, inner sounds are heard. But, when progress is made, more and more subtle [sounds] are heard.
