"Thus all the Yogas have had their place and served a useful purpose and it will become apparent that any return to Hatha Yoga practices or those practices which deal specifically with the development of the centres, brought about through various types of meditation practices and breathing exercises, is, from a certain aspect, a retrogression. It will be found that through the practice of Raja Yoga, and through assuming that point of directional control which is to be found by the man who centers his consciousness in the soul, the other forms of Yoga are unnecessary, for the greater Yoga automatically includes all the lesser in its results, though not in its practices."
