Read the commentary
Yoga : samadhi or concentration of mind. Held fast : restrained from rushing into ways which are opposed to the sastra. It is only when they are restrained by firmness (of the intellect) that they do not rush into ways which are opposed to the sastra. The meaning of the passage is this : He who, by unflinching firmness, restrains the activities of thought (manas), of life-breaths and sense-organs, restrains them by Yoga.*
That is to say, one can restrain these activities by the firmness only which is every accompanied by samadhi, by concentration of mind in the Brahman. By mere firmness, which is not so accompanied by samadhi, one cannot invariably restrain them.—A.
