He who is called ananda rupam amritam and raso vai sah by the Srutis, that also encourage the jivas to relish this rasa by saying rasam hyevayam labdhanandi bhavati, that Original Personality of Godhead Vrajendranandana is the topmost shelter of that rasa, or the akhila rasamrita murti, the embodiment of all transcendental flavours. And although He is the akhila rasamrita murti, the sringara rasa is the main flavour here and He is that flavour personified. sringarah sakhi murtiman iva (Jayadeva). sringara rasa rajamaya murtidhara; ataeva atma paryanta sarva citta hara (C.C.) “He embodies the king of transcendental flavours, namely eros, and thus He steals the hearts of everyone, including Himself.” This sringara is rasa-rata, the emperor of all flavours, that contains an endless variety of astonishing relish. Without the aid of bhakti it is absolutely impossible to relish the sweetness of the Lord, and for relishing the sweetness of sringara rasa it is imperative to take shelter of a madhura bhava. Taking shelter of the lotus feet of the supreme shelter of madhura rasa, Sri Vrishabhanu-nandini, accomplishes the limit of astonishment in relish. Just as on the one side the Radha-kinkaris relish the endless sweetness of Sri-Sri Radha-Madhava by taking shelter of Sri Radha’s lotus feet, similarly Sri Radharani infuses all the relishable sweet rasa within the kinkaris that take shelter of Her lotus feet. The light that Srila Kaviraja has shone on this makes this subject matter very easy to understand:

radhara svarupa – Krishna prema kalpalata; sakhigana hoy tara pallava pushpa pata
Krishna lilamrite yadi latake sincaya; nija seka hoite pallavadyera koti sukha hoy (C.C.)

“Radha’s svarupa is that of a wish-yielding vine of love for Krishna, and Her sakhis are its leaves, sprouts and flowers. When the nectar of Krishna-lila showers this vine the leaves and twigs feel millions of times more pleasure than if they had been sprinkled themselves.” 
(Srila Ananta das Babaji)
