“What we think about, expands.” Marc Allen
My Inspired Comment:
Any thoughts, even the ones that are never desired, and dreaded are invisible (quantum) energy forms.
Thoughts cannot ultimately be totally controlled. In analogy, not any more than anyone can control the wind.
But it is important to learn to control our reactions to them. As we respond to them in any way, we feed them energy of our own.
With sufficient energy, the thought-forms take shape and become more of a living reality to be manifested.
Therefore, if able, be discriminative of the thoughts and ideations you dwell on.
