Ahimsa!

« Whereas a good deed should call forth approbation and a wicked deed disapprobation, the doer of the deed, whether good or wicked always deserves respect or pity as the case may be. "Hate the sin and not the sinner" is a precept which, though easy enough to understand, is rarely practised, and that is why the poison of hatred spreads in the world. This ahimsa is the basis of the search for truth. I am realizing every day that the search is vain unless it is founded on ahimsa as the basis. It is quite proper to resist and attack a system, but to resist and attack its author is tantamount to resisting and attacking oneself. For we are all tarred with the same brush, and are children of one and the same Creator, and as such the divine powers within us are infinite. To slight a single human being is to slight those divine powers, and thus to harm not only that being but with him the whole world. »
