Krsna is known as Sarva-Shaktiman; He is the possessor of all energies. And Radharani is Sarva-Shakti. So, she is possessed by Krsna. Krsna attracts everyone. That’s why he has the name Krsna, all-attractive reservoir of pleasure; but Radharani is able to attract even Krsna.
So therefore, she has special qualities. Radharani brings out in Krsna the most complete experience of loving exchanges. So He was one; he became two to expand more pastimes but in the spiritual world, everything is personal…all energies, all, everything. Even the trees, the animals, the birds, the bees, they all speak.. they’re all people. And the supreme person is Krsna, but His supreme energy is Radha.
So, in the Bhagavatam, and in the Caitanya Caritamrita, She is also called the universal mother. I remember, when I was a Bhakta. I raised my hand and I wanted to ask Prabhupada a question about Radharani and He said, “Who are you?” Who are you to ask about Radharani?
So, Radharani is very special. It’s a very big offence if we think that she is an ordinary woman. Krsna’s pastimes may appear similar to human activities; but that’s as far as it goes. If you go deep into it, you’ll see that He’s not…His experience is completely on a different level. A level of pure love.
So, Radharani and Krsna, they exchange this love. All the other devotees, also in the spiritul world, they have different degrees of love that they expand, that they exchange. So the source of that love, the source of that transcendental pleasure, is Radharani.HH Jayapataka Swami Lecture – Radhastami Day
