In a situation like this, it can be so hard to know what to do. Lacking other practical options, and having no way to protect those who have already been harmed, it can be easy to be overtaken by intense anger and other destructive emotional states.
In our grief over the tragic loss of these beautiful lives we may find solace in knowing that no evil, not even death itself can harm their immortal souls. For they are forever the precious children of our Lord.
This tragedy forces me to ask the same question that Guru Nanak asked in response to atrocities committed against innocent civilians - "eti mar pai karlane tai ki dard na aaiaa (O God! Didn't you feel pain upon witnessing such a slaughter?)."
