Yoga Sutra 3.05 the light of knowledge prajna

Sūtra III.5

From mastery of that, the light of knowledge (prajñā)

From mastery of that, the light of knowledge. From mastery of that saṃyama from securing firmness in it, there is the power of manifesting the desired object, as if a light were being shone on it, there comes the light of samādhi-knowledge. On whatever the saṃyama is set firm, of that very thing the samādhi-knowledge becomes firm. By that light of samādhi-knowledge, which can illuminate anything even hidden or remote, the yogins see clearly what they have in mind, as if it were set on the palm of their hand.
