Adhyāya 48: Brahmopadeśa on Prāṇāyāma, Sāttvika Vṛtti, and the Sattva–Kṣetrajña Question
प्राणायामैरथ प्राणान् संयम्य स पुनः पुनः । दशद्वादशभिर्वापि चतुर्विशात् परं तत:
prāṇāyāmair atha prāṇān saṁyamya sa punaḥ punaḥ | daśadvādaśabhir vāpi caturviṁśāt paraṁ tataḥ ||
风神（Vāyu-deva）说道：以调息（prāṇāyāma）之法反复摄持诸生命之气——或行十次，或行十二次的息控——修行者便超越二十四谛，而证得第二十五谛：至上我（Paramātman）。

Educational Q&A
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.
