Humans are designed for 2 things:
– to work
– to work for greater good, and not sensual indulgence. This is called Yajna in Hindu philosophy
All diseases – mental and physical – happen because we do what we are not designed for.
If you want to get rid of any disease – in self or society – the first step must be to make yourself addicted to your nature – doing hard work for greater good.
The beauty of life is such that what you give comes back with a multiplier. The Yajna will reap massive benefits for you.
