Gaudiya Vaishnavism (also known as Chaitanya Vaishnavism and Hare Krishna) is a Vaishnava religious movement founded by Chaitanya Mahaprabhu (1486–1534) in India. "Gaudiya" refers to the Gauḍa region (present day Bengal/Bangladesh) with Vaishnavism meaning "the worship of Vishnu or Krishna". Its philosophical basis is primarily that of the Bhagavad Gita and Bhagavata Purana.
The focus of Gaudiya Vaishnavism is the devotional worship (bhakti) of Radha and Krishna, and their many divine incarnations as the supreme forms of God, Svayam Bhagavan. Most popularly, this worship takes the form of singing Radha and Krishna's holy names, such as "Hare", "Krishna" and "", most commonly in the form of the Hare Krishna (mantra), also known as kirtan. The movement is sometimes referred to as the Brahma-Madhva-Gaudiya sampradaya, referring to its traditional origins in the succession of spiritual masters (gurus) believed to originate from Brahma. It classifies itself as a monotheistic tradition, seeing the many forms of Vishnu or Krishna as expansions or incarnations of the one Supreme God, adipurusha.
According to Gaudiya Vaishnava philosophy, consciousness is not a product of matter, but is instead a symptom of the soul. All living beings (jivas), are distinct from their current body - the nature of the soul being eternal, immutable, and indestructible without any particular beginning or end. Souls which are captivated by the illusory nature of the world (Maya) are repeatedly reborn among the various (8,400,000 in number) species of life on this planet and on other worlds in accordance to the laws of karma and individual desire. This is consistent with the concept of samsara found throughout Hindu belief.
