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 ||
ระหว่างนาฑีทั้งสองนั้น มีนาฑีชื่อว่า “สุษุมณา” กล่าวไว้ เป็นทางเดินที่ละเอียดอย่างยิ่งและลี้ลับที่สุด พึงรู้ว่าอยู่ในอธิษฐานของเทพพรหมา
Sanatkumāra (teaching Nārada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
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.
