The derivation of the word Krsna is given in these words (Mahabharata, Udyoga-parva 71.4):krsir bhu-vacakah sabdo
nas ca nirvrti-vacakah
tayor aikyam param brahma
krsna ity abhidhiyate
"The word 'krs' is the attractive feature of the Lord's existence, and 'na' means spiritual pleasure. When the verb 'krs' is added to the affix 'na', it become Krsna which indicates the Absolute Truth."
This verse indicates how the two syllables "krs" and "na" are joined to make the name Krsna. The word "bhu-vacakah" here refers to the way the verb "bhu" is thus changed into the noun "bhava"(being) by the agency of the kvip-pratyaya affix. As the verb "bhu" is thus changed to become "bhava" so the verb "krs" to attract becomes "akarsana" (attraction). Thus "krs" means "He who attracts the hearts of others." The words "tayor aikyam," mean "As two lovers join, so the two syllables "krs" and "na" (bliss) join. When united in this way they create the meaning "all-attractive bliss". - Gopal Champu
