Yoga succeeds through six qualities: enthusiasm, courage, perseverance, knowledge of truth, determination, and renunciation of excessive company.

Complementing the previous verse on obstacles, Svātmārāma enumerates the six qualities that lead to success:

1. Utsāha — Enthusiasm. The genuine impulse and joy in practice, not forced but natural.

2. Sāhasa — Courage, audacity. The willingness to face the unknown and overcome one’s limits.

3. Dhairya — Perseverance, patience. The capacity to continue despite difficulties and lack of immediate results.

4. Tattva-jñāna — Knowledge of truth. Correct understanding of the principles of yoga, not blind practice.

5. Niścaya — Firm determination. Unwavering conviction in the chosen path.

6. Jana-saṅga-parityāga — Renunciation of excessive company. Time alone for internalization.

These verses 17-18 form a complementary pair that balances warning (what destroys) with positive guidance (what to cultivate).
