Radha, also called Radhika, Radharani and Radhikarani, is the childhood friend and lover of Krishna in the Bhagavata Purana, and the Gita Govinda of the Vaishnava traditions of Hinduism. Radha is almost always depicted alongside Krishna and features prominently within the theology of today's Gaudiya Vaishnava sect, which regards Radha as the original Goddess or Shakti. Radha is also the principal object of worship in the Nimbarka Sampradaya, as Nimbarka, the founder of the tradition, declared that Radha and Krishna together constitute the absolute truth. Radha's relationship with Krishna is given in further detail within texts such as the Brahma Vaivarta Purana, Garga Samhita and Brihad Gautamiya tantra. Radha is one of the most important incarnations of the Goddess Lakshmi.
