Radhastami, the appearance day of Srimati Radharani, Lord Krishna’s pleasure-giving potency and eternal consort.

Srila Prabhupada explains, “We pray to Radharani because She is the pleasure potency of Krishna. Krishna means ‘all-attractive,’ but Radharani is so great that She attracts Krishna. So today we should try to understand the position of Srimati Radharani and offer our obeisances to Her.

  radhe vrndavanesvari
vrsabhanu-sute devi
  pranamami hari-priye

‘I offer my respects to Radharani, whose bodily complexion is like molten gold and who is the queen of Vrindavan. You are the daughter of King Vrsabhanu, and You are very dear to Lord Krishna.’

“Radharani is hari-priya, ‘very dear to Krishna.’ Approaching Krishna becomes very easy when done through Radharani, through the mercy of Radharani. If Radharani recommends, ‘This devotee is very nice,’ then Krishna immediately accepts us, however great a fool we may be. Because we have been recommended by Radharani, Krishna accepts us. Therefore in Vrindavan you’ll find all the devotees chanting Radharani’s name more than Krishna’s. Wherever you’ll go, you’ll find the devotees are addressing one another with, ‘Jaya Radhe!’ They are glorifying Radharani. They’re more interested in worshiping Radharani than in worshiping Krishna, because however fallen I may be, if some way or other I can please Radharani, then it will be very easy for me to understand Krishna.

“Otherwise, if you try to understand Krishna by the speculative process, it will take many, many lives. But if you take devotional service and just try to please Radharani, Krishna will be gotten very easily, because Radharani can deliver Krishna. She is such a great devotee—the emblem of the maha-bhagavata, the greatest devotee.” (Lecture on Radhastami, August 29, 1971, London, adapted from BTG, Sep/Oct 2014)

Srila Raghunatha dasa Gosvami prays,

bhajami radham aravindam netram
  smarami radham madhura smitasyam
vadami radham karuna bharardram
  tato mama nyasti gatir na kapi

“I worship Sri Radha, who has eyes like lotus flowers. I remember Sri Radha, who smiles so sweetly. I glorify Sri Radha, who is full of mercy. I have no destination but Her.” (Stavavali, Sri Visakhanandabhidha-stotra 131)
