CC Madhya 9.30
- kṛṣir bhū-vācakaḥ śabdo
- ṇaś ca nirvṛti-vācakaḥ
- tayor aikyaṁ paraṁ brahma
- kṛṣṇa ity abhidhīyate
kṛṣiḥ—the verbal root kṛṣ; bhū—attractive existence; vācakaḥ—signifying; śabdaḥ—word; ṇaḥ—the syllable ṇa; ca—and; nirvṛti—spiritual pleasure; vācakaḥ—indicating; tayoḥ—of both; aikyam—amalgamation; param—supreme; brahma—Absolute Truth; kṛṣṇaḥ—Lord Kṛṣṇa; iti—thus; abhidhīyate—is called.
“‘The word “kṛṣ” is the attractive feature of the Lord’s existence, and “ṇa” means spiritual pleasure. When the verb “kṛṣ” is added to the affix “ṇa,” it becomes “Kṛṣṇa,” which indicates the Absolute Truth.’
This is a verse from the Mahābhārata (Udyoga-parva 71.4).
