There are people who are in prisons who say, 'Oh, now we don't want to be in violence', but there are so many more outside who are causing problems to society and that is why we need to give this spiritual education to people.
We need to educate people on how to be calm, how to handle their negative emotions and how to handle their mind, because neither at home, nor at school did anyone teach us how to handle our mind.
So then there is anger, jealousy and hatred, and when you live with these emotions then you act on them. You don't know how to get rid of it. You hold on to it and then you act from that and then you regret. This is the problem.
These practices and this knowledge here is the solution.
