Quantum physics and the making up of magic
Quantum physics is about the scientific observation that particles can be in two states at the same time: energy (and "waves") and matter (particles).
Those who are magical thinkers are delighted to be able to (in their minds at least) access the "quantum field" (a bunch of energy in a sense), as if it is something we can attach a spigot to and have fictional things flow, of "universal knowledge" or "energy we can grab and use.
What is a quantum leap?
1, (physics) The discontinuous change of the state of an electron in an atom or molecule from one energy level to another.
2, (metaphorical) An abrupt, extreme change.
(Wiktionary)
A particle orbiting around another particle "spontaneously" without adding energy "jumps" to a higher orbit. Note that this is not likely to happen to you. You can, however, work create extreme change, but it must be in a number of non-instant steps taken quickly to systematically create extreme change. Since we are not orbiting particles with net positive or negative charges, we must endure time and effort to get what we want.
However, some people put forth the idea that since we can generate electricity ("vibes") we can affect the quantum field. Not likely!
However, a credible person I know has seen a Hindu master create bread in his hand from nothing. Don't hold your breath on this one, as you are unlikely to get to that level without the intense training of your mind to do telekinesis at a very high level, beyond just moving objects and bending spoons with our minds.
For now, stick to physical "cause and effect"
Epigenetics - Affecting Our DNA through our behavior and thinking
Yes, this is proven, as each thing we do or think causes a chemical reaction, and thus can, usually from alot of repetition, turn on or turn off a switch in our DNA that could do such things as cause a gene to cause a susceptibility to cancer and vice versa.
But when we look at things from a "quantum perspective", we are getting into mystical or magical thinking. Instead, what we are actually doing is to just look at things from a higher perspective, using facts and tying them together to create some desired effect.
You are the one responsible
The danger of magical thinking or even of leaving things up to a Higher Entity is that it will cause one to be passive, expecting somehow that someone or something else will "do it for them". That creates a Dependency mind, a victim way of thinking, that we must avoid at all costs (as it will cost us much of our life if we don't avoid it!).
To create success in one's life, it is mandatory that one "be" 100% Responsible for one's life!!!
