Blended reading (Sanskrit + English inline)
kṛṣir bhū-vācakaḥ śabdo ṇaś ca nirvṛti-vācakaḥ tayor aikyaṁ paraṁ brahma kṛṣṇa ity abhidhīyate
“ ‘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.’
Purport
This is a verse from the Mahābhārata (Udyoga-parva 71.4).
