From the seven hundred
एवमुक्त्वार्जुनः सङ्ख्ये रथोपस्थ उपाविशत्विसृज्य सशरं चापं शोकसंविग्नमानसः
evam uktvārjunaḥ saṅkhye rathopastha upāviśat visṛjya saśaraṃ cāpaṃ śokasaṃvignamānasaḥ

“So saying, in the middle of the battlefield, Arjuna let his bow and his arrows fall, and sank down onto the floor of his chariot, his heart sinking into grief.”

Bhagavad Gita 1.47
In plain terms

At the most important moment of his life, Arjuna stops. He puts the weapon down and sits on the floor of his chariot, in the middle of the field, with two armies watching.

The tradition kept this scene in full. The lowest point was never edited out, because the whole conversation that follows grows from it. The Gita actually begins at rock bottom.
