The Gita: Srimad Bhagwadgita: श्रीमद्भगवद्गीता : Chapter 1:31-1:35

You are Arjuna yourself. There are are thousands of things, which as a child are impregnated in your mind which become your belief system for life and rule your behaviour throughout. In every doubtful endeavour, commencement of journey, every failure one unconsciously finds oneself linking the results or situations to irrelevant things.. like good or bad omens, inability of others, planetary hurdles, cat, dogs and even gods :-) So what if Arjuna talks about omens?
