" When you strike a tuning fork you activate it to send out a particular sound or frequency. Now, in a room filled with tuning forks— only those that are tuned to the exact same frequency will begin to vibrate in response. They will automatically connect and respond to the frequency that matches their own. So the idea here is to tune yourself to resonate at a frequency that is in harmony with what you want to attract. In order to create a positive future, you need to keep your energy, thoughts, and feelings in the positive range. "
