श्री भगवान उवाच
क्षुद्रं हृदय दौर्बल्यं त्यक्त उत्तिष्ठ परंतप (2.3)
Arjuna collapses on his seat crying, not wanting to fight his family and friends. Krishna says, "Shun this petty weakness of the heart and rise, O Parantapa!".
Since Arjuna has decided to fight a war, it becomes his duty to fight, irrespective of who's on the other side. Because if he doesn't, his team loses. Likewise, once you willingly choose a path, it's your bounden duty to work towards achieving it. "Weakness is sin. Weakness is death", said Swami Vivekananda. Remember?
Also, notice how Krishna addresses Arjuna- Parantapa, conqueror of enemies or the one who has control over his senses. Both are equally perfect in this context. The Gita, besides being an exquisite piece of poetry, teaches us life skills, the sine qua non for everything we do today and which are sadly, not a part of the curriculum. Here, we're talking about the art of communication, a quintessential leadership trait. It's all about striking the right chord to get things done. Krishna successfully persuades Arjuna to rise up, putting to rest his sadness, fear and unwillingness to fight. That's what effective communication leads to- success.
