Bhagavad-gītā As It Is · Text 1.3
The armies gather; conches sound
पश्यैतां पाण्डुपुत्राणामाचार्य महतीं चमूम् ।
व्यूढां द्रुपदपुत्रेण तव शिष्येण धीमता ॥ ३ ॥
paśyaitāṁ pāṇḍu-putrāṇām
ācārya mahatīṁ camūm
vyūḍhāṁ drupada-putreṇa
tava śiṣyeṇa dhīmatā
O my teacher, behold the great army of the sons of Pāṇḍu, so expertly arranged by your intelligent disciple the son of Drupada.
