You may wonder how such a simple word can produce a development of the moral qualities. The reason is given by Freud, the psychologist who has specially analyzed for us the workings of the Group Mind. "A group," he says, "is subject to the truly magical power of "names" or words. Words can provoke the most formidable tempests in the group-mind and are also capable of stilling them. And again he says, "Reason and argument are incapable of combating certain words or formulae. These words are uttered in solemnity in the presence of groups and as soon as they have been pronounced all heads are bowed with respect". Note this faculty of the group-mind carefully. Realize that man's mind is after all a group-mind, that it is a collection of thoughts (many milliards of them). It is a collocation of these thoughts, and you will find reason enough to apply by analogy all the postulates of Group Psychology to the individual Human mentation.

Thus, you see the AUMN in the auto-suggestion of Karma-Yoga to still all worries. But in the use of the AUMN do not seek for results, continues the Gita. Do not expect any particular effect to follow on the utterance. To do so would first of all be to distract the attention and lessen the efficacy of the AUMN and secondly it would be a diversion away from the AUMN. Do the work of pronunciation or utterance of the AUMN and do nothing else. Avoid extensions of the thought suggested, if any, by AUMN by the very pronunciation itself; centralize entirely on the AUMN. Thus use every mantra, use it as an auto-suggestion, affirming it to yourself by repetition and not by forcing it on your subconscious. Let the AUMN, in time, form part of your being, replacing the thoughts of worry that had occurred, that may occur, unless superseded by the utterance of the AUMN. This was the word (sound) that was, that has to be, has to prevail and be uttered. In the beginning, it was the word that was with God, i. e. with what is beyond behind phenomena (such is the sense of "God" taken here), the word that is God (as far as our pragmatic experience goes), stilling all worries, solacing all grief.

In the modern times, the value of Yoga with its preventive and curative effects is being increasingly recognized. Yoga, a Sanskrit word for 'union', means an experience of oneness or union with your inner being (self). This union, is the mind uniting with the body and breath to attain a higher level of consciousness. The integrated approach of mind and body control leads to ultimate physical health and happiness, together with the achievement of mental peace and tranquility.

Prana refers to vital air or energy, and Yama is the control and direction of that energy. Pranayama therefore, is the control and direction of this vital energy via steady breathing. Steady breathing increases the prana in the body, resulting in good health.
