A belief is simply a thought which has been thought so often that it has manifested physically into “proof” and then that proof helps you to back up the thought with acceptance, trust and expectation. That acceptance, trust and expectation in a thought is a belief. A belief is basically an assumed truth. Beliefs are not true or false, they are simply beneficial or detrimental. Our subjective realities always become the manifestation of what we expect and we expect according to our beliefs. So, in order for our realities and lives to change, we must change our beliefs.
