Gossip is a weapon used against whomever one wants to do damage. The beauty is it does not have to be true. The more outrageous the gossip the more believable! If someone knows gossip they feel empowered. If they are able to pass it on they feel they are doing service.
The Bhagavagita takes place on a battlefield. Arjuna is disturbed because he is pitted against his relatives. Krishna assures him he must fight. The Yoga Scene is the battlefield and it is our Dharma to go into battle.
