Yoga Sutra 3.28 samyama on the Pole Star
Sūtra III.28
(From saṃyama) on the Pole Star, knowledge of their motions
Making saṃyama on the Pole Star, he would apprehend the motions of the stars. Then if he made saṃyama on the celestial chariots, he would come to know them.
(From saṃyama) on the Pole Star, knowledge of their motions. And thereafter (after making the moon-saṃyama) immediately Making saṃyama on the Pole Star, he will apprehend the motions of the stars – how they converge and how they separate. How at this time this planet is opposed by that one, and how it comes thus to be subdued, and then in that way it rises again – by these means he comes to know, for instance, the good and bad fortune of the living beings.
And similarly with other things. If he made saṃyama on the celestial chariots, he would come to know them, their various kinds, and courses, and all about them.
