"To do Simran" is the physical act of sitting in a cross-legged position and meditating, uttering or chanting "Naam" - the name of God. The process brings calmness to the mind and allows one to concentrate on the "image" or "qualities" of God. The process is to allow one to "connect" to the Creator and "realise" His qualities. Sikhs prefer the name "Waheguru" to other names of God. Sometimes, the person doing simran will do this as part of a group or individually. Early morning is normally the preferred time although no one time period is considered more sacred than another.
