ei pañca sthāyī bhāva haya pañca 'rasa'
ye-rase bhakta 'sukhī', kṛṣṇa haya 'vaśa'
ei pañca—these five kinds of transcendental mellow; sthāyī bhāva—permanent ecstatic moods; haya—become; pañca rasa—five kinds of transcendental mellow; ye-rase—in a particular mellow; bhakta sukhī—a devotee becomes happy; kṛṣṇa—Lord Kṛṣṇa; haya—becomes; vaśa—under the control.
"These five transcendental mellows exist permanently. The devotee may be attracted to one of these mellows, and thus he becomes happy. Kṛṣṇa also becomes inclined toward such a devotee and comes under his control.
