। ॥ ३३६ ॥
In plain words
Check the pull outward, and the mind grows calm. When the mind is calm, the Supreme Self comes into view. See that clearly, and the bondage of this world simply falls away. So restraining the outward-going mind is itself the path to freedom.
Close to the Sanskrit
When the external is restrained, tranquility of mind [arises]; when the mind is tranquil, vision of the Supreme Self [arises]; when that is well seen, destruction of worldly bondage [follows]. Restraint of the external is the pathway to liberation.
