So you're here because you want to know what The Secret is right? Well in a very broad sense, it's all about the law of attraction, that like attracts like so what you give out, the universe will give back to you.
It tells you that all you have to do in order to have everything you want in life, is to put the thoughts in your mind that will bring these things to you or "you're ability to think things into being". Think good, positive thoughts and in so doing good, positive things will come to you. It goes a step further and tells you to live life like you've already achieved what you want. All the wealth, the happiness, the love, the friends, the good health that you ask for, is yours if you truly believe that it is - not that it CAN BE yours, that it IS yours. And don't worry it doesn't tell you what to do - and then leave you hanging. It gives you these simple instructions:
Step 1 - Ask
Step 2 - Believe
Step 3 - Receive
These concepts are not new and in fact have been practiced by some of the greatest minds and successful people in human history. In The Bible Matthew 7:7 - "Ask, and it will be given to you; seek and you will find.." and Mark 11:24 - "Therefore I tell you whatever you ask in prayer, believe that you have received it and it will be yours..". The Secret uses quotes and advice from the likes of Dr Martin Luther King "Take the first step in faith. You don't have to see the whole staircase. Just take the first step" and Buddha "All that we are is a result of what we have thought". Current favourite Dr Joe Vitale says "You want to become aware of your thoughts and choose your thoughts carefully...because you are the masterpiece of your own life" and the ever youthful best in the business Bob Proctor "See yourself living in abundance and you will attract it. It works every time with every person."
So now you've had a taste of what is possible as proven by those who are living "The Secret" you really need to read the book yourself. For me at the very least its reaffirmed what I already felt - that our thoughts, our state of mind determine our actions and our lifes path. The Secret has become my bible, I carry it with me at all times because its mere presence inspires me and puts a smile on my face. If all it takes is a happy thought then why not? Beats the alternative doesn't it!
