Creative visualization is a cornerstone of using the Law of Attraction, and meditative exercises are part of this process. For example, you are encouraged to spend 10-15 minutes a day on building an increasingly detailed image of the life you want to develop. However, visualization actually extends far beyond these mental pictures, and can be practiced in concrete ways every day. For example, you will learn writing exercises here on our site and artistic approaches that focus on externalizing your goals and making them more real. You can be as creative in your visualization process as you like, and trying out the basic skills may inspire you to come up with unique methods that are even more effective.
When you understand the law of attraction works by delivering you experiences that you are a match to now energetically, you come to realize the importance of feeling good now, and not putting all your focus on the undesirable bits of "what is." This doesn't mean pretending to be okay with things you don't like, but actually adopting a different perspective, and actually feeling better.
