4. Experience, Direct Perception and Realisation
If experiences are disclosed in speech or writing, then they decrease or stop.
And this happens to many.
That is 
why the Yogins never tell their experiences to anybody or tell only when they are firmly established.
But if you tell them to the Mother, they will not decrease, but increase.
You must get settled in the habit of telling the experiences to the Mother.
