The ultimate aim of all yoga, at-one-ment with the Supreme Lord, is the focusing point of this study of comparative yoga. All the important forms, ancient and modern, are taken in turn, their practices explained and discussed, and to the extent to which each can lead us toward the final goal is evaluated. The standard for comparison is Surat Shabd Yoga, the Crown of Life, the highest form of yoga. Religious parallels and various modern movements are cited.
I have read this book more than once. I often go back and read passages that are relevant to my current spiritual questions regarding meditation.
Sant Kirpal Singh is a beautiful writer. He explains and clarifies many complex and esoteric spiritual concepts so that the seeker will have a truthful understanding of the aim and purpose of yoga.
Chapter 5: Surat Shabd Yoga p. 145 "In His Nameless state He is neither light nor darkness, neither sound nor silence, but when He assumes shape and form, Light and Sound emerge as His primary attributes.
...The Word or Shabd as it descends downward assumes a varying density of spirituo-material forces.
...As a river springing from the snowy peak of a towering mountain flows toward the sea, it undergoes many changes of setting, shape, motion and appearance, and yet its waters remain the same.
If one could discover this audible life-stream within oneself, if one could discover its lower reaches, one could use it as a pathway leading inevitably to its source."
P. 147 "Only one who has himself experienced what the great scriptures describe, can guide us to their real significance. But the task of a spiritual teacher does not end there. The elucidation of the true meaning of religion is no more than a first step. After the aspirant has understood the nature of his goal, he must pursue it practically and rationally. To know is one thing, and to do is quite another...So too the spiritual guide at the time of initiation gives the disciple a first-hand experience of the inner Light and Sound. He puts him into touch with the Divine Stream, be it at its lowest level, and instructs him in the sadhnas to be followed for consolidating and developing this inner experience to its full extent."
