What is "gurunath"

Gurunath is a commonly used term when praising what is considered by devotees the ultimate source of compassion, love and truth - irrespective of sectarian divides whether they may be devotees of Shiva, the Lord of Transformation in the Hindu pantheon ( Shaivaite) or of Vishnu, the Lord of Preservation and Sustenance in the Hindu pantheon ( Vaishnav) or any other devotee ( bhakta) of a Hindu God or Goddess.

The first part of the refrain "Bolo Sri Sat Gurunath Maharaj ki" is chanted by the leader of the kirtan, bhajan, devotional chanting of religious scriptures or highly devotional compositions made by individuals respectively, or devotional discourse. Then the congregation responds in unison with "Jai!". This refrain, which is normally chanted at the end of a bhajan or kirtan, may be translated from Sanskrit as "Say/Chant/Proclaim ("Bolo") the name of the Spiritual Mentor who is the essence of Truth ("Sri Sat Guru") who is Lord ("Nath") and King ("Maharaj")..."Yes!""
