पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras The one-pointedness of the Chitta is when it grasps in one, the past and present. How are we to know that the mind has become concentrated? Because time will vanish. The more time vanishes the more concentrated we are. In common life we see that when were are interested in a book we do not note the time at all, and when we leave the book we are often surprised to find how many hours have passed. All time will have the tendency to come and stand in the one present. So the definition is given, when the past and present come and stand in one, the more concentrated the mind. 13. एतेन भूतेन्द्रियेषु धर्मलक्षणावस्थापरिणामा व्याख्याताः ॥ १३ ॥ etena bhootendriyeshu dharmalakshanavastha parinama vyakhyatah By this is explained the threefold transformations of form, time and state, in fine or gross matter, and in the organs. By this the threefold changes in the mind-stuff as to form, time, and state are explained. The mind-stuff is changing into Vrttis, this is change as to form. To be able to hold the changes to the present time is change as to time. To be able to make the mind-stuff go to the past forms giving up the present even, is change as to state. The concentrations taught in the preceding aphorisms were to give the Yogi a voluntary control over the transformations of his mind-stuff which alone will enable him to make the Samyama before named. 103
