Sympathy is what you have for someone after they die, pity you have for someone when they don't have a date to the biggest dance of the year. Empathy is what I do to you when you judge me. Envy is having pity on yourself. Can you discern the rest for yourself?
I can not give you the reference of Ram Chandar or Krishna, because they were not historical figures. I can not help it but to present to you the names of (Hazrat) Abu Bakar (RA) and (Hazrat) Umar Farooq (RA). They were leaders of a vast Empire, yet they lived a life of austerity.
