The moon functions as a receptacle of the same light to the greatest degree. According to the mystical point of view, if it were not for the moon the whole cosmos would go to pieces, for the reason that the central currents of the sun are functioning in the moon, which reflects the light of the sun in fullness. Only the difference is that, as it is the reflection of the sun -- although in its fullness -- it has finer currents of light, it is soft and cooling, attractive, and its light is beautiful. Therefore the light of the sun is called jelal by the Sufis, and the light of the moon jemal. The former expresses power, and the latter beauty. The former is creative; the latter is responsive.
