Haṭha Yoga Pradīpikā / 4.18 The rest are pointless

4.18

Haṭha (हठ) Yoga Pradīpikā (प्रदीपिका)

द्वासप्ततिसहस्राणि नाडीद्वाराणि पञ्जरे ।
सुषुम्णा शाम्भवी शक्तिः शेषास् त्वेव निरर्थकाः
dvāsaptatisahasrāṇi nāḍīdvārāṇi pañjare |
suṣumṇā śāmbhavī śaktiḥ śeṣās tv eva nirarthakāḥ

The line

Seventy-two thousand doors of channels are in the cage. Suṣumṇā (सुषुम्णा) is the Śāmbhavī (शाम्भवी) śakti (शक्ति). The verse says the rest are pointless.

नेपालीमा

पिँजडामा नाडीका बहत्तर हजार ढोका छन्। सुषुम्णा शाम्भवी शक्ति हो। श्लोकले बाँकी व्यर्थ हुन् भन्छ।

Where it sits

The seventy-two thousand return from 1.41. The nirarthaka (निरर्थक) is the verse's own, said of every channel besides the middle.

Split: dvā (द्वा) + saptati (सप्तति) + sahasrāṇi (सहस्राणि) nāḍī (नाडी) + dvārāṇi (द्वाराणि) pañjare (पञ्जरे) / suṣumṇā (सुषुम्णा) śāmbhavī (शाम्भवी) śaktiḥ (शक्तिः) śeṣās (शेषास्) tv (त्व्) eva (एव) nirarthakāḥ (निरर्थकाः)
