ISKCON belongs to the Gaudiya-Vaishnava sampradāya, a monotheistic tradition within the Vedic or Hindu culture. Philosophically it is based on the Sanskrit texts Bhagavad-gītā and the Bhagavat Purana, or Srimad Bhagavatam. These are the historic texts of the devotional bhakti yoga tradition, which teaches that the ultimate goal for all living beings is to reawaken their love for God, or Lord Krishna, the "all-attractive one".
God is known across the world by many names including Allah, Jehovah, Yahweh, Rama, etc. ISKCON devotees chant God's names in the form of the maha-mantra, or the great prayer for deliverance: Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare / Hare Rama Hare Rama, Rama Rama, Hare Hare.
