Hindu rituals and routines are an important part of Hindu culture and tradition. Some key rituals and their meanings include lighting lamps to signify knowledge and spirituality, having prayer rooms as dedicated spaces for worship, greeting with Namaste which represents the divine in each person, showing respect to elders by prostrating before them, and applying marks on the forehead for religious significance. Feet are also considered sacred so they should not touch papers, books or people, as that is seen as an act of disrespect.
