Many people, upon discovering they are addicted to something or another, will try to purify themselves by purifying their home. They will pour out all the alcohol in their house, they will flush the drugs down the toilet, they will throw away all their cigarettes, get rid of their marijuana, destroy their television, or in other ways attempt to purify themselves by purifying their home.
However, they mistake home for self. Purification of home does not result in purification of self. Liquor, once poured out, can be replaced, brought back into the house by the drunkard. Drugs, flushed down the toilet, can be replaced, brought back into the house. The smoker will get new cigarettes.
When the drunkard has conquered their thirst, their home will remain free of alcohol. Such victory occurs only after difficulty.
