Śaṅkarācārya's commentary

Practice consists in the repetition of one and the same idea, uninterrupted by any other thought, with reference to Me, the sole object of your thought. Such a practice is itself said to be Yoga. With the mind thus solely engaged in Yoga, not passing over to any other object, the Yogin who meditates according to the teaching of the scripture and of the teacher — of the śāstra and ācārya — reaches the Puruṣa, the Transcendental Being in the Solar Orb.
