Radha-Krishna are collectively known within Hinduism as the combined forms of feminine as well as the masculine realities of God. With Krishna, Radha is acknowledged as the Supreme Goddess.
Each and every god has its partner or Shakti, and without this Shakti, is sometimes viewed as being without essential power. It is a not uncommon feature of Hinduism when the worship of a pair rather than one personality constitutes worship of God.
It is said that Krishna is only satiated by devotional service in loving servitude and Radha is the personification of devotional service to the supreme lord. Various devotees worship her with the understanding of her merciful nature.
It is believed that Krishna enchants the world, but Radha enchants even him. Therefore, she is the supreme goddess of all and together they are called as Radha-Krishna.
Radha lived in a village called Repalli which was a little away from Vrindavan. Radha was five years elder than Krishna. She was in love with Krishna from a younger age.
Radhakrishna is not any romantic relationship or simply the combination of the feminine and the masculine: it symbolizes the soul seeking the Divine Love.
According to another belief, Radha represented Jeevatma while Shri Krishna is the Paramatma. Radha's selfless love was the highest form of devotion. And therefore, she merged into Shri Krishna by surrendering herself.
Do you know what is Krishna's love word? “To love without condition, to talk without intention, to give without reason, care without expectation, that's the spirit of true love.”
