Bg 1.46

sañjaya uvāca
evam uktvārjunaḥ saṅkhye
rathopastha upāviśat
visṛjya sa-śaraṁ cāpaṁ
śoka-saṁvigna-mānasaḥ
Synonyms: 
sañjayaḥ uvāca — Sañjaya said; evam — thus; uktvā — saying; arjunaḥ — Arjuna; saṅkhye — in the battlefield; ratha — of the chariot; upasthe — on the seat; upāviśat — sat down again; visṛjya — putting aside; sa-śaram — along with arrows; cāpam — the bow; śoka — by lamentation; saṁvigna — distressed; mānasaḥ — within the mind.
Translation: 
Sañjaya said: Arjuna, having thus spoken on the battlefield, cast aside his bow and arrows and sat down on the chariot, his mind overwhelmed with grief.
Purport: 

While observing the situation of his enemy, Arjuna stood up on the chariot, but he was so afflicted with lamentation that he sat down again, setting aside his bow and arrows. Such a kind and soft-hearted person, in the devotional service of the Lord, is fit to receive self-knowledge.

Thus end the Bhaktivedanta Purports to the First Chapter of the Śrīmad Bhagavad-gītā in the matter of Observing the Armies on the Battlefield of Kurukṣetra.
