Former Home Minister and Congress veteran Shivraj Patil, facing bitter criticism by the BJP for "Hindu hatred" over his recent remark that the concept of jihad was not just in Islam but also in Bhagavad Gita and in Christianity, today sought to firefight the controversy saying jihad is an act of killing anyone who speaks the truth. Lord Krishna also taught lessons of jihad to Arjun in a part of Gita in the Mahabharat, he had said.
