There are people who claim that avoiding alcohol is fanatical, thus they drink to "prove" they are not "fanatics." By that reasoning, they should also fornicate, take drugs, murder, rob, and in general perform all the other actions that lead to suffering.
And who are these idiots who seek to negotiate with Satan? Listen, my friends! With the sinister demon Algol, it is impossible to make compromises, arrangements, or any kind of crooked deal. Alcohol is very treacherous and sooner or later will stab us in the back.
As you can see in the medicine book, there are medicinal uses for alcohol, but in very small doses. Yet once again, many people drink it for "medicinal purposes," when in reality they are drinking it because of desire for it.
You should also understand that all that theosophist material was for the previous era.
