idk 2013, I do believe in absolute non-injury. And again, injury is not just physical. You can injure a person mentally, through your thoughts and words. This is a subtle field. About Elbert Einstein, I have deep respect for his contribution in science but Vedas are beyond Einstein's thought. In other words, where quantum physics ends Vedas starts. Also, don't try to mix two worlds: Material & Bhramic world. These two worlds are opposites. From the Bhramic standpoint, how can you injure something that is immortal? In material world, injury do make sense but not in the Bhramic world. To an enlightened sage, this world is a dream. The only reality is Bhraman where there is no pairs of opposite such as love & hate, likes & dislikes etc etc. Be at peace. Enjoy your Dashain with Tika, jamara and aashirvad.
