Adhyāya 48: Brahmopadeśa on Prāṇāyāma, Sāttvika Vṛtti, and the Sattva–Kṣetrajña Question
प्राणायामैरथ प्राणान् संयम्य स पुनः पुनः । दशद्वादशभिर्वापि चतुर्विशात् परं तत:,दस अथवा बारह प्राणायामोंके द्वारा पुनः-पुनः प्राणोंका संयम करनेवाला पुरुष भी चौबीस तत्त्वोंसे परे पचीसवें तत्त्व परमात्माको प्राप्त होता है
prāṇāyāmair atha prāṇān saṁyamya sa punaḥ punaḥ | daśadvādaśabhir vāpi caturviṁśāt paraṁ tataḥ ||
Vāyu-deva said: By repeatedly restraining the vital breaths through the disciplines of prāṇāyāma—whether by ten or by twelve such breath-controls—a practitioner goes beyond the twenty-four principles and attains the twenty-fifth principle, the Supreme Self (Paramātman).
वायुदेव उवाच
Repeated prāṇāyāma and restraint of prāṇa lead the practitioner beyond the twenty-four material principles (tattvas) to realization of the twenty-fifth principle, the Supreme Self (Paramātman/Puruṣa).
Vāyu-deva is instructing a listener on yogic practice and metaphysical ascent, explaining how disciplined breath-control functions as a method for transcending the constituents of nature and reaching the highest spiritual principle.
