When the mantra wheel is attached to the home, it can only have the effect of seeking good fortune and avoiding evil. It is impossible to eliminate one's own karma and common karma. For example, disasters in nature are the common cause of mankind. This is a fact, and it can't be changed by a few symbols. It is your heart that really solves problems, truly repents, and is truly pure and compassionate. Confess the past, the key is not to recreate it in the future! This is Buddhism!
