The 'Power of Positive Thinking', the 'Vortex' and the 'Law of Attraction' are based on manifesting material effects through directed thought. Magick, in either it's 'white' or 'black' forms is about accomplishing the same. The first three use a 'sciency' explanation and the last two use a more spiritual one, but if you practice any of these, you know they work.
If you are a 'Law of Attraction' person, do not look down your nose at Wicca. While employing similar methods, it is actually much less concerned with self and wealth and is much more imbued with an attitude of gratitude.
While I agree that these methods are effective, I would suggest forgoing all of the above and instead opting for a meaningful relationship with the person that created all this. If you are a practitioner, you already know that there is more to this world than meets the eye. Think that truth through and see where the logic leads you. Are you willing to trade short term happiness for long term joy?
There is no evidence for a creatorlet's talk about this creator
If what you are practicing produces 'something from nothing', then you are practicing magick. Someone may have dressed it up in a white physics lab coat, but in reality it's the same. Quantum mechanics does not bend to your will and localize the appropriate particles in your driveway to manifest a BMW. When you attempt to 'play God' in this manner, you are harnessing powers you do not understand to effect powerful changes, the extent of which you can neither predict or control. It can be done. People do it every day.
Does it not seem like extreme hubris to think that we can 'control' these forces? Does it not seem arrogant to think that we can 'use' the universe in this manner, especially with no consequences? Should we not be asking some questions about the source of this power? About the cost?
To trust in God is to allow Him to work his 'magic' for our ultimate good. Taking the reins ourselves because 'we know best' seems not only arrogant, but short sighted. Wouldn't the Creator of the universe want the best for us? Wouldn't He also be uniquely positioned to see the pitfalls of giving us what we want, as opposed to what we need?
Just because something can be done, that doesn't necessarily mean it should be done. Please tread carefully here. Or better yet, you might want to walk away.
