Science and Metaphysics
Metaphysical energies are not thought constructs. They really exist, and are observable and controllable.
The problem is that they are not objectively visible, and also mostly immeasurable. They are visible only in the effects - if certain energies work through us, we adjust our environment accordingly.
Metaphysical and mystical energies are felt - not through our emotions, but through a subtle perception, to which all are capable.
