If you are a practitioner of meditation and have achieved a silent mind, if your intuitive capacities have opened and stabilized, or if you are an intuitive by nature, then perhaps the best way for choosing the right product for you is by using the symbols as guides.
If you feel an attraction towards a specific character(s) then it is highly likely that you will benefit from a recharge of the qi-aspect it represents. If you feel neutral, or are repelled by a symbol, then you should not use that product.
Below are the symbols of each qi product. The names are left out so as to avoid conditioning of your intuitive response. By clicking on the symbol you will be taken to the product page.
