In Sikhism, Waheguru is the most widely used name for God, describing the Supreme Being as a universal, genderless deity. Despite having many words to describe the Divine, Sikhs believe in only one God and seek to hold Waheguru in mind at all times. Waheguru is otherwise known as Sat Nam (true name) and Akal Purkh (eternal being).
In both Sikhism and Kundalini yoga, Waheguru also refers to a mantra which can be chanted to call upon divine light to remove spiritual darkness. It is used as a means to elevate and awaken the spirit, whilst expressing the bliss one feels when moving from ignorance and illusion to wisdom or enlightenment.
