International Yoga Day: Swami Vivekananda's Views on Yoga and Pranayama

A series of exercises, physical and mental, is to be gone through every day, until certain higher states are reached. Therefore it is quite necessary that we should find a posture in which we can remain long. That posture which is the easiest for one should be the one chosen. For thinking, a certain posture may be very easy for one man, while to another it may be very difficult. We will find later on that during the study of these psychological matters a good deal of activity goes on in the body. Nerve currents will have to be displaced and given a new channel. New sorts of vibrations will begin, the whole constitution will be remodelled as it were. But the main part of the activity will lie along the spinal column, so that the one thing necessary for the posture is to hold the spinal column free, sitting erect, holding the three parts — the chest, neck, and head — in a straight line. Let the whole weight of the body be supported by the ribs, and then you have an easy natural postures with the spine straight. You will easily see that you cannot think very high thoughts with the chest in...

After one has learned to have a firm erect seat, one has to perform, according to certain schools, a practice called the purifying of the nerves. This part has been rejected by some as not belonging to Raja-Yoga, but as so great an authority as the commentator Shankarâchârya advises it, I think fit that it should be mentioned, and I will quote his own directions from his commentary on the Shvetâshvatara Upanishad: "The mind whose dross has been cleared away by Pranayama, becomes fixed in Brahman; therefore Pranayama is declared. First the nerves are to be purified, then comes the power to practice Pranayama. Stopping the right nostril with the thumb, through the left nostril fill in air, according to capacity; then, without any interval, throw the air out through the right nostril, closing the left one. Again inhaling through the right nostril eject through the left, according to capacity; practicing this three or five times at four hours of the day, before dawn, during midday, in the evening, and at midnight, in fifteen days or a month purity of the nerves is attained; then begins Pranayama."
