While our tradition provides numerous methods for healing, including: runes, mantras, sexual magic, pranayama, intense prayer, transmutation, and sacred rites, there are many cases of individuals with emotional problems that are so severe that strictly performing these practices to the best of their ability cannot fully counteract the strength of their problem.
While esoteric practice is essential for any transformation, some people with extreme disorders, such as manic depression, emotional disturbance, etc., require extra help on a biochemical level, since their karma has already crystallized into physical, emotional or mental illnesses. Everything requires balance and judgment in terms of treating such ailments, since while some individuals may succeed on a strict and powerful regiment of esoteric exercises, others may require anti-psychotic or anti-depressant medications to help achieve stability.
I know the case of one Gnostic student who is schizophrenic and tried to heal himself exclusively with runes, sacred rites, pranayama, etc. While he managed to last for a few months, he quickly relapsed and became ill again. It was only with a combination of anti-psychotic medication and transmutation, meditation, sacred rites, etc., that he was able to achieve balance, since his mental illness had already crystallized into his physical brain as a neuro-chemical imbalance requiring treatment on a bio-chemical level, not just in the mental or spiritual planes.
Therefore, each individual must follow their Being and be practical. If one needs medication, then so be it. A disciple is not obstructed from obtaining gnosis as a result of a chemical imbalance, and can succeed in yoga and meditation even while being medicated.
Joyful in hope, suffering in tribulation, be thou constant in thy prayer.
Benedictis, qui venit in nomine Domini. Osanna in excelsis.
"Blessed is he who comes in the name of the Lord. Hosanna in the highest!"
