हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

36 HAṬHAYOGAPRADĪPIKĀ and resembles the second kind of Prāṇāyāma. Kevala Kumbhaka is the same as Kumbhaka Prāṇāyāma. 72. As long as one does not achieve Kevala Kum- bhaka, one should practise Sahita. The Sahita should be practised till the Prāṇa enters Suṣumnā, which is known by a peculiar sound being produced in the Suṣumnā. Then he should practise only ten or twenty Sahita Kumbhaka-s. and increase the Kevala Kumbhaka-s to eighty. 72-73. Without exhalation or inhalation, when the breath is retained with ease, this sort of Prāṇāyāma is called Kevala Kumbhaka. 73-74. When this Kevala Kumbhaka has been mastered without any exhalation or inhalation, there is nothing unattainable by him in the three worlds. 74-75. He who is fully competent through this Kevala Kumbhaka, through the control of breath, obtains even the stage of Rāja-yoga. There is no doubt about this. 75. Through Kumbhaka, the Kuṇḍalinī is aroused; through arousing Kuṇḍalinī, the Suṣumnā is free of all obstacles, and perfection in Haṭha-yoga is obtained. 76. One cannot obtain perfection in Rāja-yoga without Haṭha-yoga, nor [perfection] in Haṭha-yoga without Rāja-yoga. So both should be practised till perfection [in Rāja-yoga] is obtained. 77. At the end of the retention of breath in Kumbhaka, the mind should be made free of objects. By thus practising, the stage of Rāja-yoga is reached.
