The word Suka means, a parrot. Yes, he was the Parrot that plucked the ripe nectar-filled fruit called Bhagavatam from the Tree of the Vedas and enabled the world to taste it and be nourished by it. May the world relish the fruit and strengthen itself through it, and derive the Atmic Bliss that it can confer. ((Bhag Vahini, p. 232)
