This festival celebrates the appearance of Lord Chaitanya Mahaprabhu. It is observed annually (in late February, early March) by Krishna devotees all over the world—especially in the area of Mayapur, India, the place where He appeared in the year 1486.
Lord Caitanya Mahaprabhu is Krishna Himself in the mood of Radharani, appearing as His own devotee, to teach us that we can gain full enlightenment simply by chanting the holy names of the Lord:
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/
Hare Rama, Hare Rama, Rama Rama, Hare Hare
Those who witnessed the Lord’s pastimes saw Him dance and chant with ecstatic love for God, the likes of which had never been seen before. Lord Chaitanya encouraged everyone to follow this same process. He taught that anyone—regardless of background or spiritual qualification—can develop their innate love of God and experience great spiritual pleasure by chanting the Hare Krishna mantra.
The present-day International Society for Krishna Consciousness continues the work begun by Lord Chaitanya, who predicted that the chanting of the holy names of Krishna would spread all over the world.
Gaura Purnima means “golden full moon,” signifying that:
1) Lord Chaitanya was “born” during a full moon, and
2) The Lord blesses everyone with the soothing, moonlike rays of His sublime teachings.
His followers generally observe this festival by fasting and chanting the holy names all day. At moonrise, a vegetarian feast is offered to the Lord and then enjoyed by all.
