One should engage oneself in the practice of yoga with determination and faith and not be deviated from the path. One should abandon, without exception, all material desires born of mental speculation and thus control all the senses on all sides by the mind.

The practitioner must completely abandon all desires born of mental willing, and use the mind itself to rein in the senses from all directions. The mind is both the source of bondage (through desire) and the instrument of liberation (through discipline).
