What is "gyani"

A Gyani or Giani is an honorific Sikh title used by someone learned in the Sikh religion and who often leads the congregation in prayers, such as Ardas, or in singing ( kirtan). The word "Ghian" in Punjabi means knowledge, derivative of Sanskrit word, Jnana. So a "gyani" is someone who has spiritual and religious knowledge and can help the congregation, called the Sadh Sangat, in understanding the Sacred Texts and the history of the religion.
