There are four types of Regrets:
1. Regret that spans over a day e.g. When a person leaves his home without eating.
2. Regret that spans over a year, just like the negligence shown when cultivating.
3. Regret that spans over a lifetime, when a man and his wife are unsuited to each other.
4. Regret that is eternal, which is when your Creator is unhappy with you.
