Some people always get this wrong, not everything is relating to a spiritual issue especially gambling, it's more relating to a mental issue than something spiritual for instance you shouldn't be referring an addicted gambler to the church or spiritual home for prayers, rather such cases should be handled by a mental health practitioner, psychologist or the rightful professionals to handle the situation, your spiritual leader or teacher is just a religious leader meant to handle spiritual cases and not the right one to handle such cases, I don't know about other societies but I've seen people in my region make such errors and it needs to be addressed.
every one who loses in the gambling have their own believes about gambling so we need to let some people know that getting addicted in the gambling is not all about a spiritual sometimes but all about what you desire to engage into, if you passion on something else people will think that they is a mystery behind why theirs no mystery behind it, it base on the passion you have for it that make the person to be over willing
