Query: Very Helpful for deep thinking work

I have several Monroe Products CDs. All contain the hemi-synch wave technology patterns that form the foundation of many of The Monroe Institute's outreach and human development programs.Indigo falls into the "brain food" category, in that it is designed specifically to help get your mind in a focused state for specific, deep thinking tasks, such as calculations and analysis, technical reading and design, etc... It is very effective for this, in my experience. It is repetitive by design, so if you are looking more for meditative or relaxing music that contains the hemi-synch technology, there are other options TMI offers that are better for those goals, such as Inner Journey.
