Spiritual World: Goloka Vrindavan

                            Q. It is stated that all the Vishnu forms are eternal. Are there separate lokas for the Kurma, Matsya, Varaha, Narasimha, Rishabhadev, Parasurama forms? If so why does the Bhagavatam say that the form of Narasimha was never seen by anybody before? And also what about the form of Lord Caitanya? If He is eternal, where is His planet?
