Yoga is destroyed by these six causes: overeating, excessive effort, talking too much, rigid adherence to rules, company of worldly people, and inconstancy.

This verse enumerates the six obstacles (ṣaḍ-doṣa) that destroy progress in yoga:

1. Atyāhāra — Overeating. Digestion consumes energy that could be used for practice.

2. Prayāsa — Excessive effort. Practice should be steady but not forced.

3. Prajalpa — Talking too much. Speech disperses prāṇa and agitates the mind.

4. Niyamāgraha — Rigid adherence to external rules. Obsession with external rituals without inner understanding.

5. Jana-saṅga — Worldly company. Relationships with people not interested in the spiritual path can divert us.

6. Laulya — Inconstancy or restlessness. Practice requires regularity and commitment.

These obstacles are as relevant today as they were six centuries ago.
