Over the past I have used Holosync and Hemisync for various meditations and only once did I have a situation that my mood did get rather angry. ( flash back to the past) Yet I wanted to help a child of mine to have a healthier life and I asked the people at the Monroe Institute about a product that maybe she could use and was advised because of her condition not to use Binaural technology with her. So I opted to use a product called Sound Health Sound Wealth by Luanne Oaks. Available thru Learning Strategies and my daughter and myself absoulutely love the product and it seems to have done miracles for her.
