Serapis, The Master

The Master Serapis, frequently called the Egyptian. He is the Master upon the fourth ray, and the great art movements of the world, the evolution of music, and that of painting and drama, receive from Him an energising impulse. At present He is giving most of His time and attention to the work of the deva, or angel evolution, until their agency helps to make possible the great revelation in the world of music and painting which lies immediately ahead. More about Him cannot be given out, nor can His dwelling place be revealed.
