Mokṣopāya: Bhakti-rooted Jñāna and the Aṣṭāṅga Yoga of Viṣṇu-Meditation
एतयोरुभयोर्मध्ये सुषुम्णा नाडिका स्मृता । अतिसूक्ष्मा गुह्यतमा ज्ञेया सा ब्रह्मदैवता ॥ २३ ॥
etayorubhayormadhye suṣumṇā nāḍikā smṛtā | atisūkṣmā guhyatamā jñeyā sā brahmadaivatā || 23 ||
ಆ ಎರಡು ನಾಡಿಗಳ ಮಧ್ಯದಲ್ಲಿ ‘ಸುಷುಮ್ನಾ’ ಎಂಬ ನಾಡಿ ಪ್ರಸಿದ್ಧ. ಅದು ಅತಿಸೂಕ್ಷ್ಮವೂ ಪರಮ ಗುಹ್ಯವೂ; ಬ್ರಹ್ಮದೇವತೆಯ ಅಧಿಷ್ಠಿತವೆಂದು ತಿಳಿಯಬೇಕು.

It highlights Suṣumṇā as the central, most secret pathway of inner ascent—subtler than the side channels—indicating that liberation-oriented practice depends on directing awareness and prāṇa through this hidden middle channel.
While primarily yogic, it supports bhakti-sādhana by implying inward concentration: devotion becomes steadier when the mind is gathered into the central channel (suṣumṇā), enabling deeper absorption in the chosen deity.
This is not a Vedāṅga passage (like Vyākaraṇa or Jyotiṣa); it instead conveys yogic technical knowledge (nāḍī-śāstra/prāṇa-vijñāna) used for disciplined meditation and breath regulation.
