Identifying one specific area of your life that you would like to improve is a great idea. As you do this, using the chakra chart below, what Hz level corresponds with that? Once you determine that, choose an audio file that you will listen to each and every night before going to sleep.
For example, if you are aware of the fact that guilt plays a large part in your life, you may very well benefit from fine tuning the Root Chakra. To do this, choose an audio file that focuses on the 396 Hz solfeggio frequency and listen to it each and every night. Visit this page for easy access to an audio file that focuses on each of these seven solfeggio frequencies.
