Krishna is a name of the original, unique Supreme Person, the source of all that exists. Krishna appears as other forms of God avatars to create and maintain the universe, while He simultaneously enjoys loving relationships with His countless associates in the spiritual world. He visits this material world from time to time to free His devotees from material existence and to vanquish the wicked. He performs superhuman pastimes lifting mountains, swallowing forest fires, and killing numerous extraordinarily powerful demons as easily as a child playing with toys.
