Truth in and of itself is independent of written or spoken words.
Ideally..
By yourself.
Whatever you read, hear or even perceive based on energy, should be checked accordingly.
On the contrary.
And so, it is no different on the Energy-based level than you know it from the material-based dimension; not everything you read or hear is true.
Truth is also independent of any professional opinions or technical expertise.
It is independent of the competence of the teacher or author confirmed by others.
