पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras just as in brutes and idiots; it only acts to injure others. No other idea comes into that state of mind. Then there is the active state of mind, Rajas, whose chief motives are power and enjoyment. “I will be powerful and rule others.” Then, at last, when the waves cease, and the water of the lake becomes clear, there is the state called Sattva, serenity, calmness. It is not inactive, but rather intensely active. It is the greatest manifestation of power to be calm. It is easy to be active. Let the reins go, and the horses will drag you down. Anyone can do that, but he who can stop the plunging horses is the strong man. Which requires the greater strength, letting go, or restraining? The calm man is not the man who is dull. You must not mistake Sattva for dullness, or laziness. The calm man is the one who has restraint of these waves. Activity is the manifestation of the lower strength, calmness of the superior strength. This Chitta is always trying to get back to its natural pure state, but the organs draw it out. To restrain it, and to check this outward tendency, and to start it on the return journey to that essence of intelligence is the first step in Yoga, because only in this way can the Chitta get into its proper course. Although this Chitta is in every animal, from the lowest to the highest, it is only in the human form that we find intellect, and until the mind-stuff can take the form of intellect it is not possible for it to return through all these steps, and liberate the soul. Immediate salvation is impossible for the cow and the dog, although they have mind, because their Chitta cannot as yet take that form which we call intellect. 12
