I pray to Lord Nrsnghadeva that whoever is behind this is caught and rewarded by the Government! What cowards, killing innocent women, children and devotees because they want something material? Move then to someplace else; don't throw bombs in the temple!
But it is a greater problem than this. Srila Prabhupada said the next Great War will be started by Pakistan, according to reliable sources. What to do but chant Hare Krishna with great sincerity, which unfortunately I have yet to do.
My sincerist and most heartfelt condolences to all the Vaishnavas of the Lord at this time especially in Manipura who are experiencing such great loss.
