All forms are fundamentally same
The One Divine Principle works through many forms in order to manipulate and complete the process Srishti (creation). All forms are fundamentally of the same essence. There is no higher or lower. All are equally divine. When God comes down assuming special form on special occasions for a specific purpose, He is known as Avatar. Each Avatar is born as a consequence of Divine Will and with the purpose of restoringDharma and moral life.
