Spiritual teachings and teachers declare emphatically not to harm the world and other beings!
I add, not to harm also ourselves, our body, mind and soul.
If we cannot do any good for the world and humanity at least, let no harm them.
Let's begin with our ourselves, here and now let's stop harming our body, mind and soul.
How can we respect others if we do not respect ourselves? How can we avoid harm others, if we harm ourselves?
