Paṇḍita means learned, and budha means one who is well-versed. He is called budha. Budha, this very term, you'll find in another place of Bhagavad-gītā, in the Tenth Chapter, budhā bhāva-samanvitāḥ.
- ahaṁ sarvasya prabhavo
- mattaḥ sarvaṁ pravartate
- iti matvā bhajante māṁ
- budhā bhāva-samanvitāḥ
- (BG 10.8)
That budha you'll find in the Tenth Chapter, and the same budha, paṇḍita, paṇḍita and budha. Paṇḍita, according to Bhagavad-gītā, paṇḍita. Paṇḍita means learned man. The Sanskrit word paṇḍita means... And budha is "well-versed."
Now who is well-versed? And who is paṇḍita? A very learned man from, by academic education, may not be a learned man according to the view of Bhagavad-gītā. Bhagavad-gītā says, "He is the learned man who can see everyone on the equal footing, equal level."
