Ratri definition
Ratri means night and night brings rejuvenation. According to Vedic sci- ence, matter reverts back to its original form to recreate itself again and again. The creation is cyclical, not linear; everything is recycled by nature- a continu- ous process of rejuvenation. The human mind, however, lags behind in this rou- tine cycle of creation.
Ratri means night, the time for Mahashivarathri. It is the wedding of the and mind, and you need peace in the soul.
