The Guru is the Ladder, the Guru is the Boat, and the Guru is the Raft to take me to the Lord's Name. The Guru is the Boat to carry me across the world-ocean; the Guru is the Sacred Shrine of Pilgrimage, the Guru is the Holy River. If it pleases Him, I bathe in the Pool of Truth, and become radiant and pure.
— Sri Guru Granth Sahib
