How does alcohol affect spiritual health?

My husband has the drink habit, not all the time, but periodically, the periods becoming more frequent―

How do you explain this?

As a general thing, this comes from something that is more or less of an obsession. 

Nine-tenths of those addicted to the drinking habit, owing to the effect of alcohol on the psychic centres, are more or less open to the astral world and to persons in the astral who have passed over because of drink, or who have spent their earth-life in drinking and still desire to have the sensation of drink through more or less sensitive people on the physical plane. 

This can be obtained vicariously through another by obsessing or throwing the desire over him and causing him to drink.

There is but one way to treat this. 

The victim must demand―

In the name of the Living Christ―

All entities shall keep way from him, so that they cannot obsess him or give him the desire for drink. 

If you can explain this to your husband and get his co-operation in it, it would be well. 

For very often, this fact awakens in one the manly idea that he will not suffer for the sake of giving someone else such satisfaction or relief, and he will, therefore, refuse to drink when the feeling comes over him.

The reason it seems to come a little oftener now than previously is because there is such a great fight to maintain this old idea that a person has a right to drink if he wants to. 

If it is possible to replace this with―

Thou shalt, namely, thou shalt strive for higher things and not permit obsessing entities to force you to do something your higher self does not approve of―

if this can be impressed upon him, he will cure himself. 

Do not worry over it―

Do not comment upon it. 

Do not blame him―

Do not blame him for what he does, but try to help him to strengthen his forces against the entitised powers that are striving to make him a mere tool to satisfy their appetites.
