This is by Swami Satyananda, who I've made a particular study of. My conclusion is that you need to read him with your filters on. He knows a LOT (and is generous enough to spill it), but he speaks with equaly confidence about things he knows and things he's just been told. He contradicts himself a bunch (in this site, he says both that raja yoga can result in schizophrenia upon kundalini awakening and that it does not result in schizophrenia upon kundalini awakening). Basically, he wrote this stuff when he was young, and he had the brio of youth and early recognition.
Now that he's older, he's admitted he never really felt God until recently. A rather courageous admission (which endears me to him), and one that should be beared in mind when reading his prolific early writings. He has not, to my knowledge, written anything in recent years, unfortunately.
