The Meditation tone is designed to take you into a deep state of meditation and hold you there for a 60 min period. during the audio you will hear the tone spiking, this is to prevent you from sinking into a state of sleep and will assist in your control and investigation of the entrained state.
The file is set between 5Mhz and 3Mhz with occasional spikes to 6Mhz well within the desired range for meditation.
This is the main file used for my own meditation and has been proven to have a deep and lasting effect on the mind .
The Lucid Dreaming meditation Audio is designed to keep the user in 'State' by spiking the file into Gamma from Theta - Once again the file is available as a download and can be ordered from this page .
