over 1500 years ago the great indian sage, Patanjali, compiled these yoga aphorisms as a help and guide to his fellow humans. in the cosmic scheme of things 1500 years is the blink of an eye, and so it is these wise sayings remain fresh and workable for the modern lover of spiritual wisdom. the aphorisms stand on their own as originally given to the world. succint, vital, the feel of eternal truth is in them. to read and meditate on these sayings is to go another step closer to your own realization that indeed, it is only ignorance which stops us from seeing the reality of the Atman as One with eternal Brahman, the "satchitananda" or existance, conciousness, bliss, the eternal ground of all that is or ever could be. this beautiful classic is further enhanced by the translation and commentaries of the dynamic duo, swami prabhavananda and christopher isherwood. modern ideas about god and truth come and go, this book has stood the test of time and remains ever new because it's true. i highly recommend this little book to anyone interested in the light that comes when Truth is seen.
