Arhatic Yoga level 8 and higher
Arhatic Yoga level eight and higher, deal with GOD realization and of this nothing can be said publicly. These higher Arhatic levels have not been taught by MCKS to any of his senior disciples, because none of them are ready for these higher spiritual teachings.
The way Arhatic Yoga levels have been categorized is different now than it was five to seven years ago. Five to seven years ago, the sublevels of Arhatic Yoga were categorized as separate Arhatic levels by themselves.
