I read some lines more to understand the subtle point you were making. Excretion point was hitting hard and hurts ego and forces to reevaluate and recalibrate our notions of guru and paths.  

Very deep point and non-obvious point. 

Will hurt and question all the sects and ego of the methods to complete eradication of ignorance and purity of psyche by limited entities. Exceptions are Lord Buddha and other similar entities, but lay entities has to go thru it.
