kṣetrajñaḥ karaṇī jñānaṃ karaṇaṃ tena tasya tat
niṣpādya muktikāryaṃ vai kṛtakṛtyaṃ nivartate //

"(When the Yogi has accomplished this stage, he acquires) discriminative knowledge, which is the means of enabling living soul, when all the three kinds of apprehension are destroyed, to attain the attainable supreme Brahma. Embodied spirit is the user of the instrument, which instrument is true knowledge; and by it that (identification) of the former (with Brahma) is attained. Liberation, which is the object to be effected, being accomplished, discriminative knowledge ceases. When endowed with the apprehension of the nature of the object of inquiry, then, there is no difference between it (individual and) supreme spirit: difference is the consequence of the absence of (true) knowledge. When that ignorance which is the cause of the difference between individual and universal spirit is destroyed finally and for ever, who shall ever make that distinction between them which does not exist? Thus have I, Kháńd́ikya, in reply to your question, explained to you what is meant by contemplative devotion, both fully and summarily. What else do you wish to hear?"
