I interpret Ernest’s statement about wholeness as the fundamental paradigm of Science of Mind (SOM). In the first clause in the statement, Ernest states quite simplify and completely the basic rule of SOM for all practitioners. All practitioners must know that wholeness is all there is. In the second clause, he presents the conundrum of healing. He is telling us that healing is based on perception. So, the statement is actually a falsehood that looks like a truth but the falsehood is only revealed to those who understand his teaching of the SOM.
In his teachings, he is consistently telling students that there is nothing that needs to be healed. He says that we only need to know the wholeness of all things and in all things their truth is revealed. The question I ask myself from this teaching is how I would apply this in a practical application? If I was asked to do a treatment for someone to be healed I would treat that their truth is already revealed and that there is no illness and only my perception must be treated.
