पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras
Why should there be repetition? We have not forgotten that
theory of Samskaras, that the sum-total of impressions lives
in the mind. Impressions live in the mind, the sum-total of
impressions, and they become more and more latent, but
remain there, and as soon as they get the right stimulus they
come out. Molecular vibration will never cease. When this
universe is destroyed all the massive vibrations disappear, the
sun, moon, stars, and earth, will melt down, but the vibrations
must remain in the atoms. Each atom will perform the same
function as the big worlds do. So the vibrations of this Chitta
will subside, but will go on like molecular vibrations, and
when they get the impulse will come out again. We can now
understand what is meant by repetition. It is the greatest
stimulus that can be given to the spiritual Samskaras. “One
moment of company with the Holy makes a ship to cross this
ocean of life.” Such is the power of association. So this
repetition of Om, and thinking of its meaning, is keeping good
company in your own mind. Study, and then meditate and
meditate, when you have studied. The light will come to you,
the Self will become manifest.
But one must think of this Om, and of its meaning too. Avoid
evil company, because the scars of old wounds are in you, and
this evil company is just the heat that is necessary ot call them
out. In the same way we are told that good company will call
out the good impressions that are in us, but which have
become latent. There is nothing holier in this world than to
keep good company, because the good impressions will have
this same tendency to come to the surface.
