Rituals—a tradition of customs, rites and ceremonies—have been a part of religious sects and orders since times immemorial. Across centuries of change and development, the modern man still is allied with his ancestors through these enduring rituals. From the basins of Mesopotamia to the ghats of the Ganges, rituals have celebrated the spirit of mankind and united people with the cause of humanity. In Srimad Bhagavad Gita, Sri Krishna expostulates the rich tradition of rituals in the Indian culture.
