Hinduism is perhaps the oldest religion in the world, with sacred texts estimated to date back to 3000 B.C. Many of its traditions have lasted for eons, with origins lost in time. A Hindu wedding, one of the most sacred of rites, incorporates many of these timeless rituals and customs. And one such tradition is that of serving the newly-weds (specifically the groom) with a glass of milk on their wedding night. Needless to mention but this tradition is extremely popular, courtesy Bollywood movies and TV serials.
