Pradyumna:
- mahātmānas tu māṁ pārtha
- daivīṁ prakṛtim āśritāḥ
- bhajanty ananya-manaso
- jñātvā bhūtādim avyayam
- (BG 9.13)
"O son of Pṛthā, those who are not deluded, the great souls, are under the protection of the divine nature. They are fully engaged in devotional service because they know Me as the Supreme Personality of Godhead, original and inexhaustible."
Prabhupāda: Yes. Bhajanti. Bhajanti means "engaged in devotional service." Bhaja sevāyām. Bhaj-dhātu, this verb, is meant for rendering service. Bhaj-dhātu, kti, bhakti. So bhakta. Bhakti, bhakta and Bhagavān. So these are the mahātmās. But these mahātmās, these bhakta-mahātmās... Actually, mahātmā is bhakta-mahātmā.
