The bipolar condition is treatable, if the one who is suffering is willing to work on it. The method to cure this takes patience and consistent effort, but it can be done. Firstly, the person has to learn the Gnostic teachings and practices, especially in regard to psychology and sexual energy. Transmutation provides the energy that will cure the illness. The daily psychological work harnesses the transmuted energy in order to transform the psyche. So all of this effort must be active daily. Then, as an additional support, the person can use the mantra S M Hon, which cures illness of the mental body. It should used with prayer, and can be used all day as a support and remembrance of oneself. It is used by extended the sounds: sssssssssss, mmmmmmmmm, hhhhhhhhooooooonnnnnnnnn. This can be aloud or silent. It will be most effective however if one sits in meditation and vocalizes it (aloud ir silently), without thinking of anything else.
Finally, I would also recommend the daily use of two additional practices: the magic of the roses, and the eucharist, which are detailed in the links below.
All of these forces together create a very powerful medicine that can rapidly restore balance and clarity in the mind of the one who is suffering.
