Yoga Sutra 3.16 knowledge of what is past and future

Sūtra III.16

From saṃyama on the three changes, knowledge of what is past and future

From saṃyama on the three changes, knowledge of what is past and future. The saṃyama is to be carried on up to the illumination of samādhi-prajñā.

Whatever object it is fixed on, it brings direct perception of that object as it really is. On whatever subtle or concealed or past or future or remote object the saṃyama is made, with the conscious intention to attain it, his purpose brings its fulfilment to the yogin.

From saṃyama on the changes of dharma, time-phase, and condition, knowledge of past and future things comes to the yogin. When dhāraṇā, dhyāna, and samādhi are made on the same thing, this is called saṃyama. By that saṃyama, the three changes being directly perceived, there is produced knowledge of things past and future which are in them, in the changes. Since all things are changeable by their conjunction with the past and the other changes, by making saṃyama on the three changes of all things, conjoined as they are with the three times, all things become directly perceived. And in that omniscient one who sees the uncertainty of what is inherently changing every moment, detachment is born.
