ei rasa-asvada nahi abhaktera gane
krsna-bhakta-gana kare rasa asvadane
ei—this; rasa-asvada—tasting of transcendental mellows; nahi—not; abhaktera gane—among nondevotees; krsna-bhakta-gane—the pure devotees of Lord Krsna; kare—do; rasa—these transcendental mellows; asvadane—tasting.
"The exchange between Krsna and different devotees situated in different transcendental mellows is not to be experienced by nondevotees. Advanced devotees can understand and appreciate the different varieties of devotional service reciprocated with the Supreme Personality of Godhead.
