' The Avatara '...

50. On the tree of Sat-Chit-Ananda there are innumerable Ramas, Krishnas, Christs, etc.; one or two of them come down into this world now and then, and produce mighty changes and revolutions.

51. The Avatara or Saviour is the messenger of God. He is like the Viceroy of a mighty monarch. As when there is some disturbance in a far-off province the king sends his viceroy to quell it; so whenever there is any waning of religion in any part of the world, God sends His Avatara there

52. It is one and the same Avatara that, having plunged into the ocean of life, rises up in one place and is known as Krishna, and diving again rises in another place and is known as Christ.
