Bhagavad Gita

ತತಃ ಶ್ವೇತೈರ್ಹಯೈರ್ಯುಕ್ತೇ ಮಹತಿ ಸೈಂದನೇ ಸ್ಥಿತೌ ।
ಮಾಧವಃ ಪಾಂಡವಶ್ಚೈವ ದಿವ್ಯೌ ಶಂಖೌ ಪ್ರದಧ್ಮತುಃ ॥೧೪॥
tataḥ śvetairhayairyukte mahati saiṃdane sthitau |
mādhavaḥ pāṃḍavaścaiva divyau śaṃkhau pradadhmatuḥ ||14||

Sloka 1:14
Gist of the sloka:
In response, Lord Krishna and Arjuna seated in their chariots pulled by white horses, blew their respective conch’s.
Once the Kauravas war noises reduced, Lord Krishna and Arjuna sitting in the biggest of the chariot pulled by 4 white horses, then blew their conch. First Lord Krishna and then Arjuna.
Lord is called “Ma-dhawa” here. “Ma” meaning Goddess Lakshmi and “Dhawa” meaning her husband. Madhawa meaning Lord of Goddess Lakshmi.
Ma also means Knowledge. Krishna being the Lord of all knowledge is known as “Madhawa”
Lord Krishna was born into the lineage of “Madhu”; hence was known as Madhwa.
The word “Mathru” is reflective of 7 great books – Rig veda, Yajur veda, Samaveda, Atharvaveda, Ramayana, Mahabharatha and all puranas. These books reflect the key knowledge of the entire sanathana dharma, all of which represents the supremacy of Lord Krishna. It is one another reason for calling him Madhawa.
Arjuna is called ‘Pandava’ here as a reflection of he being the youngest of the Pandu’s first wife Kunti’s children. The youngest usually being the recipient of all affections. He was also called “Partha”, ‘Kauntaeya’ etc., Arjuna being a friend of Lord Krishna also had increased presence of the Lord in him. He had another avatar as “Nara”.
Our body too is like a chariot. In such a chariot, there is the presence of the Lord driven by 4 vedas and with satvic [White] qualities/horses.
