Crunchy brainworm trash like this deserves ridicule and derision. In many cases it is ultimately harmless to believe in science fiction in the 21st century, but they become dangerous and harmful when they're wrapped in self-help conceit, as they are in Gruber's "work". This is not the way to enlightenment. At its core, it is at best a white appropriation of Eastern concepts, and at worst a psychotic fever dream that makes people think speaking gibberish at each other can heal the heart and soul. Steer clear of charlatans like Gruber.
