The so-called spiritual food is certainly repetitive, that's for sure. I think you could walk into a hall and take right up where you left off years ago. Well, there may be some minor differences, depending on their ever present strobe light.
I found the food to be anything but spiritual. It was often anxiety provoking and just plain abusive to the mind and spirit.
It may be served up with smiling faces and well dressed people, but in the end it bites just like a serpent.
