पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras 9. शब्दज्ञानानुपाती वस्तुशून्यो विकल्पः ॥ ९॥ shabdajnaananupati vastushoonyo vikalpah Verbal delusion follows from words having no (corresponding) reality. There is another class of Vrttis called Vikalpa. A word is uttered, and we do not wait to consider its meaning; we jump to a conclusion immediately. It is the sign of weakness of the Chitta. Now you can understand the theory of restraint. The weaker the man the less he has of restraint. Consider yourselves always in that way. When you are going to be angry or miserable, reason it out, how it is that some news that has come to you is throwing your mind into Vrttis. 10. अभावप्रत्ययालम्बना वृत्तिर्निद्रा ॥ १०॥ abhavapratyayalambana vrittirnidra Sleep is a Vrtti which embraces the feeling of voidness. The next class of Vrttis is called sleep and dream. When we awake we know that we have been sleeping; we can only have memory of perception. That which we do not perceive we never can have any memory of. Every reaction is a wave in the lake. Now, if, during sleep, the mind has no waves, it would have no perceptions, positive or negative, and, therefore, we would not remember them. The very reason of our remembering sleep is that during sleep there was a certain class of waves in the mind. Memory is another class of Vrttis, 17
