Navratri means the nine nights and the new night. Creation happens in the darkness. In the womb of the mother and underneath the soil. Nine months in the womb are like nine long nights where the spirit takes human form.
Night provides rest and rejuvenation. At night the entire creation goes to sleep including the ashram night watchman. (Laughter) People working come home at night and they really celebrate, rejoice and pray. Nine nights are precious as they have subtle energy. The subtle is enriched.
There are 64 divine mother impulses which govern the subtle creation. These are responsible for restoring all earthly and spiritual benefits. They are simply part of one's awakened consciousness. These nine nights are celebrated to rekindle those divine impulses and celebrate the innermost depth of our lives.
Cleanse your body and cleanse your soul. Cleanse your body with water and your soul with knowledge and your spirit with pranayam and kriya. There is no penance higher than Pranayam. It is the greatest penance.
