हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

FOURTH CHAPTER

1. Salutations to Śiva, the Guru, who is of the form of nāda, bindu and kalā; the person ever devoted to these obtains the stainless state [free from māyā]. This chapter is wholly devoted to Rāja-yoga. The nāda is a mystical sound similar to the prolongation of the sound of a bell and represented by a semicircle in Om. Bindu is the ṃ sound of the anusvāra in the Praṇava. Kalā is a speciality of nāda.
2. Now I shall expound the excellent process of Samādhi, that destroys death, leads to [eternal] happi- ness and confers the supreme bliss of [absorption in] Brahman. ‘Destroying death’ means enabling the Yogin to shed his body at will. This is explained later on. The happiness of a Jīvanmukta is brought about when the mind is stilled and the vāsanā-s (acquired tendencies) are destroyed. Bliss is that of Videhamukti, when the Prārabdha-karman is exhausted and a permanent union takes place between the Jīva and Parabrahman. 3, 4.
