Half of these are very ignorant, manipulable, low life, and the other half are Jews rubbing their hands together.
If you learn our teachings deeply, aka you read the whole JoS and most importantly HPHC's sermons (that elaborates on lot of things), you see these groups are nowhere compared to us.
We actually meditate, advance ourselves, help others, in contrary to these groups. Those of the left hand path vibrate some weird unknown language or hebrew a few times a day and most importantly take drugs before it to boost the effectiveness and sheit. The other half of them just sits there waiting for some miracle. One can decide which to choose.
