Hi Martin, first of all I'm glad you have had wonderfulful results with LF. Like you, I also used to use LF1 and LF7 for awhile after completing the series - I guess they were my favourites at the time
When I received the gamma tracks I particularly loved meditating to Nirvana. Since then I have amazed myself by going back to LF10/9/8 etc and noticing even more improvements in my daily life over various periods of time as I am sure you will too.
Here are some of Michael's notes which I have kept in a journal - I hope they are of use to you:-
"Awaken & Nirvana include an exciting new technology which I call "universal constant technology" which fully compliments and works along side the current Binaural, Monaural and Isochronic technology that makes up the LifeFlow Meditation Series. These gamma tracks contain a special, proprietary design addition that give them an extra little kick over and above the design of the other LifeFlow tracks.
I have chosen the 40Hz frequency because it has received the most research so far and it is intriguing because it tends to entrain the brain at multiple frequencies in accordance with the brain's own natural rhythms.
Because of this multi-entrainment aspect, a 40Hz track can be used for relaxation, meditation, creativity, study, stress reduction, and so forth equally well. This is a frequency that has had great success in dealing with conditions such as ADD.
Other frequencies tend to work best for more specific types of activities.
You can experience ecstatic states of consciousness with them. If you were of an eastern religious orientation you would refer to these states as Nirvana, Samadhi or shamanic trance. In a more common manner of speaking they would call such states "Christ Consciousness" or "Krishna Consciousness".
You will gain the most benefits if you either have some meditation experience under your belt, or have progressed into some of the deeper levels of LifeFlow, or have worked with other spiritual/metaphysical disciplines previously."
As Giles says, just meditate with the gamma tracks in the normal way you do with LF and one important fact to remember is, there are various benefits to be continually gained from all the alpha, theta and delta levels - I'm certain they will serve you well throughout your life.
I wish you an abundance of peace and joy on your continuing journey of self discovery
