By making Samyama on a particle of time and its precession and succession comes discrimination.
In plain words: By focusing deeply on a single moment of time and on the moments before and after it, the yogi gains clear discernment, the power to tell what is real from what is not.
How are we to avoid all these things, these Devas, and heavens, and powers? By discrimination, by knowing good from evil. Therefore a Samyama is given by which the power of discrimination can be strengthened. This is by making a Samyama on a particle of time, and the time preceding and following it.
Namaste.
A calm guide to life, the mind and the old teachings.
