Why is someone aggressive towards someone else? What is the reason for that?

Sri Sri Ravi Shankar: Stress. Someone who is relaxed cannot be aggressive. Sleep does not provide you that deep mental rest. Sleep only gives you physical rest. If you are agitated and you go to sleep, then even when you wake up you feel the agitation, but meditation removes that agitation. That is why even a little bit of meditation can uplift the spirit.
