Could the human heart be made luminous, and the living and throbbing organ be made visible, so as to have it reflected upon a screen, . . . then every one would see the Sun-spot phenomenon repeated every second -- due to its contraction and the rushing of the blood" (SD 1:541-2). The sunspots serve not only as vents for egress and ingress of the steams of lives in constant circulation throughout this solar system, but such solar pulsations are cosmically rhythmic and the well-being of the entire solar system is controlled by the vital and intellectual energies constantly active in and through the sun, and whose functional operations are physically expressed by the appearance and disappearance of the sunspots.
