I have been interested in visualization for many years.
I was first introduced to when I read the book You See it When you Believe It, by Wayne Dyer.
I find that it is a fascinating subject.
I irony is that even if you do not believe that it works, it is still at work all the time.
I learned the worrying is just a negative form of visualization.
There are different visualization techniques that can be used to achieve different results.
Some people compare it to daydreaming, while others insist that one must a follow a regimented set of rules and guidelines, in order for it to be legitimate.
In reality, there are no rules, and one must create their own ways of visualization.
Visualization techniques have been used to aid for relaxation.
There is a claim that they are great for healing, where the individual imagines or sees an avenger of sorts that is attacking the things that are making the person sick.
Once the villain is overcome, the person recovers from the illness.
Of course, this mostly anecdotal evidence, but scientist are trying to to prove a relationship.
Also, it has been claimed that if one can visualize the end event as already being so, then this will actually have a causal relationship to the creation of the actual event.
An example of this could be imagine the dollar amount of a check that comes from the sale of a house, an then selling the house if real life for the exact amount.
When one considers these few minor examples, it become clear that the uses of visualization are unlimited.
It is also a form of meditation, and is used with meditation.
There is a plethora of books, courses, videos and coaching programs that focus on visualization.
It can be done anywhere at anytime.
It can be helpful to be in a quiet, undisturbed atmosphere, but it can be as simple as daydreaming, or staring out a window.
If you are a commuter on a transit system, this would be an ideal time to visualize good things and it will help pass the time.
