The Secret, is The Law of Attraction, expanded.
The Law of Attraction states that like energy attracts more like energy. The frequency that you emit, will attract more energy resonating on the same frequency.
Think of your mind as a transmission tower. Broadcasting your frequencies out into the universe.
What is a frequency? Your frequency is your thoughts and emotions. Your thoughts are Vibrations, and your emotions are pure Energy. Vibrations being charged with Energy, emit Frequencies. And those frequencies are magnetic forces that are transmitted through space. This magnetic force, attracts other energies, that resonate on the same frequency.
So what does this mean?

“In order to find the secrets of the universe, one must think in terms of Energy, Frequency & Vibration.”
Nikola Tesla

It means that every single situation or circumstance in our life, we attract to us with our thoughts, feelings, and emotions.
Sending positive thoughts and emotions out into space, attracts good situations, people, & events. Sending negative thoughts and emotions attracts bad circumstances & events. Everything we have ever experienced in life, we attracted to us by virtue of how we chose to think and feel.

It also means, that we can use this power to attract everything that our hearts desire. If we are able to focus on our desires without any conflicting thoughts, and feel positive emotion towards that thought; meaning our hearts must Feel and Believe our happy thoughts, then we will be sending the magnetic frequency out into the universe to attract exactly that which we desire. If the frequency is strong and consistent, then it must magnetically draw to it, its matching frequency, making your desires a reality.

Make sure that your thoughts and emotions are in alignment with each other. Because it is the Feeling, that attracts your desires; not the thought. The thought is just the quantum blueprint; the quantum possibility. It does not have any power without the appropriate feeling to charge the blueprint to life. To make sure that your thoughts and emotions are in alignment with one another, your emotion must be in complete harmony with your thoughts. If you think of wealth, but your emotions are in doubt, debt or poverty, then you can not attract wealth. But if you feel faith and love for wealth, think thoughts of wealth and feel wealthy; you will attract wealth.

We must learn to train ourselves to Think AND Believe positive thoughts and emotions. This is education for the New Age. This is the ultimate discipline; being in control of our thoughts and emotions. Because we can not control others, or the outside world. But through our thoughts and emotions, we have complete, ultimate, and total control of ourselves and thus, our destiny.

“Everything is energy, and that all there is to it. Match the frequency of the reality you want, and you can not help but get that reality. It can be no other way. This is not philosophy, this is physics.”
Albert Einstein
