It is true that God is even in the tiger, but we must not go and face the animal. So it is true that God dwells even in the most wicked, but it is not meet that we should associate with the wicked.
If a white cloth is stained even with a small spot, the stain appears very ugly indeed. So the smallest fault of a holy man becomes painfully prominent.
The truth is that you cannot attain God if you have even a trace of desire. Subtle is the way of dharma. If you are trying to thread a needle, you will not succeed if the thread has even a slight fiber sticking out.
So long as one does not become simple like a child, one does not get divine illumination. Forget all the worldly knowledge that thou hast acquired and become as a child, and then will thou get the divine wisdom.
Wisdom leads to unity, but ignorance to separation.
So long as God seems to be outside and far away, there is ignorance.
But when God is realised within, that is true knowledge.
