KACHHA (KURAMA)(Tortoise Incarnation) Machh (Matsya incarnation), Kachh, Kurama (names of Tortoise incarnation) took birth according to the \’will of the Lord. (Maru M. 5, p. 1082) The ten incarntions were created under the Will of the Lord. (Maru M. l, p. 1037) Both the words Kachh and Kurama are applied to the Tortoise incarnation of Vishnu. Vishnu assumed the form of a tortoise at the bottom of the milk-ocean, making his back, the pivot of the mountain Mandara, which was churned by twisting the great serpent Vasuki as the rope. In this way fourteen objects (jewels) were recovered from the ocean. See : Das Avataras.
