पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras form, or an elephant form, or a man form, is not outside; all that we know is our mental reaction from the outer suggestion. Matter is the “permanent possibility of sensation,” said John Stuart Mill. It is only the suggestion that is outside. Take an oyster for example. You know how pearls are made. A grain of sand or something gets inside and begins to irritate it, and the oyster throws a sort of enameling around the sand, and this makes the pearl. This whole universe is our own enamel, so to say, and the real universe is the grain of sand. The ordinary man will never understand it, because, when he tries to, he throws out an enamel, and sees only his own enamel. Now we understand what is meant by these Vrttis. The real man is behind the mind, and the mind is the instrument in his hands, and it is his intelligence that is percolating through it. It is only when you stand behind it that it becomes intelligent. When man gives it up it falls to pieces, and is nothing. So you understand what is meant by Chitta. It is the mind-stuff, and Vrttis are the waves and ripples rising in it when external causes impinge on it. These Vrttis are our whole universe. The bottom of the lake we cannot see, because its surface is covered with ripples. It is only possible when the rippled have subsided, and the water is calm, for us to catch a glimpse of the bottom. If the water is muddy, the bottom will not be seen; if the water is agitated all the time, the bottom will not be seen. If the water is clear, and there are no waves, we shall see the bottom. That bottom of the lake is our own true Self; the lake is the Chitta, and the waves are the Vrttis. Again, this mind is in three states; one is darkness, which is called Tamas, 11
