Prince Arjuna was one of the greatest Kshatriyas(warrior) of the Mahabharata epic.
The prelude to the Mahabharata War, was a a dynastic succession tangle, between two groups of cousins(the Kauravas and Pandavas), for the throne of Hastinapura.
And, as all efforts at peace-negotiations failed, the Pandavas and the Kauravas, fought one of the fiercest wars of their times, at Kurukshetra(viz the Mahabharata War). The Mahabharata war also involved a number of ancient kingdoms participating as allies of the rival groups.
Arjuna was on the battlefield, ready to fight the greatest war of his lifetime, when he realized that he was facing the greatest "emotional" challenge of his life.
Arjuna was "besieged" by questions, for which he could not find satisfactory answers.
अहो बत महत्पापं कर्तुं व्यवसिता वयम् | यद्राज्यसुखलोभेन हन्तुं स्वजनमुद्यता: || 44||
यदि मामप्रतीकारमशस्त्रं शस्त्रपाणय: | धार्तराष्ट्रा रणे हन्युस्तन्मे क्षेमतरं भवेत् || 45||
Alas! How strange it is that we have set our mind to perform this great sin. Driven by the desire for kingly pleasures, we are intent on killing our own kinsmen. It will be better if, with weapons in hand, the sons of Dhritarashtra kill me unarmed and unresisting on the battlefield.
Arjuna placed his celestial bow, Gandiva, down on earth and said that- he did not want to fight.
सञ्जय उवाच |
एवमुक्त्वार्जुन: सङ्ख्ये रथोपस्थ उपाविशत् |
विसृज्य सशरं चापं शोकसंविग्नमानस: || 46||
Sanjay said: Speaking thus, Arjuna cast aside his bow and arrows, and sank into the seat of his chariot, his mind in distress and overwhelmed with grief.
Subsequently ,Arjuna found answers to all his questions, through the medium of Gita Upadesha(advice given in the Bhagavad Gita) by Lord Sri Krishna.
What were the sort of questions that perplexed Prince Arjuna, before the start of the Mahabharata war? Please explain in brief.
