is the Supreme Person, Krishna Himself, in the form of His own devotee. He appears in this world to spread love for Krishna through the congregational chanting of the holy names of the Lord. He appeared in Sridhama Mayapur, West Bengal, in 1486. His activities and teachings are described in detail in the book "Teachings of Lord Chaitanya" and the multi-volume "Sri Chaitanya-charitamrita." L:ord Caitanya is the combined form of Krishna and Krishna's most dear devotee, Srimati Radharani. He came to experience the love She feels for Him, and to show by example how to fully surrender to Krishna. He exhibited signs of the love of God to the highest degree, and emphasized chanting the holy names of Krishna as the best means to attain love of God.
