Bhagavad Gita Chapter 1 Sloka 20 (1.20)

ಅಥ ವ್ಯವಸ್ಥಿತಾನ್ ದೃಷ್ಟ್ವಾ ಧಾರ್ತರಾಷ್ಟ್ರಾನ್ ಕಪಿಧ್ವಜಃ ।
ಪ್ರವೃತ್ತೇ ಶಸ್ತ್ರಸಂಪಾತೇ ಧನುರುದ್ಯಮ್ಯ ಪಾಂಡವಃ ॥೨೦॥
atha vyavasthitān dṛṣṭvā dhārtarāṣṭrān kapidhvajaḥ |
pravṛtte śastrasaṃpāte dhanurudyamya pāṃḍavaḥ ||20||
Sloka 1:20
Gist of the sloka:
O Lord, Arjuna who had flag of Hanuman, seeing sons of Dhitrarastra being ready, took up and readied his bow, spoke to Lord Krishna as follows.
Explanation:
Once both sides indicated their readiness, Arjuna prepared himself for the battle. He readied his bow Gandhiva and spoke to Lord Krishna who was his charioteer as follows.
Lord Hanuman was the symbol on Arjuna’s flag; which was flying atop his chariot. Bheema [who was an avatar of Lord Vayu] was once on his way to collect ‘Sougandhika’ flowers and met another avatar of Lord Vayu – Hanuman. During the discussions, Hanuman had promised to protect Arjuna during the forthcoming war by being present atop Arjuna’s chariot, by being resident in the flag.
It is similar to Lord Prana [Lord Vayu] being ever present [and protecting] in one’s living body along with Lord Krishna and the individual soul.
Arjuna had such a Lord protecting him from top while the Lord himself being his charioteer. He had in his hands Gandhiva a powerful bow. All these made Arjuna get ego as to his invincibility giving raise to his egoistic talk to Lord, which comes next.
Lord here [in this sloka alone] means Lord of Sanjaya, King Dhritrarastra.
