It is not possible to get a clear grasp on spiritual truths unless one gets the experience of absolute truth 

at least once, for one moment, in one's life 

that one qualification distinguishes the gem from pebbles 

and any one who has not got that light of experience can never deliver anything truthfully

this is a fact of life, inescapable

it is 0 or 1

you either got it or not got it 

those who got it can gauge and find the real value of any expression 

so can skip the surface stuff 

here in i find a very very few who got it 

and they can only deliver the real without confusion
