Haṭha Yoga Pradīpikā / 4.20 Other practices are exertion

4.20

Haṭha (हठ) Yoga Pradīpikā (प्रदीपिका)

सुषुम्णावाहिनि प्राणे सिद्ध्यत्येव मनोन्मनी ।
अन्यथा त्वितराभ्यासाः प्रयासायैव योगिनाम्
suṣumṇāvāhini prāṇe siddhyaty eva manonmanī |
anyathā tv itarābhyāsāḥ prayāsāyaiva yoginām

The line

When prāṇa (प्राण) flows in suṣumṇā (सुषुम्णा), manonmanī (मनोन्मनी) succeeds. The verse says the other practices are only exertion for yogins.

नेपालीमा

प्राण सुषुम्णामा बग्दा मनोन्मनी सिद्ध हुन्छ। श्लोकले अरू अभ्यास योगीहरूका लागि श्रम मात्र हुन् भन्छ।

Where it sits

The anyathā (अन्यथा) is the verse's own. The success it names is the state of 4.4.
