A Granthi reads the Guru Granth Sahib.
The Guru Granth Sahib is always placed in the centre of a Gurudwara and placed on a raised platform, known as Takht (throne). The Guru Granth is given the greatest respect and honour. Sikhs cover their heads and remove their shoes while in the presence of Guru Granth. Before coming into its presence, they bathe and bow before the Guru Granth. The Guru Granth is normally carried on the head and as a sign of respect not touched with unwashed hands or put on the floor.
The Guru Granth Sahib is taken care of by a Granthi. He is responsible for reciting from Guru Granth and leading the Sikh prayer. The Granthi also acts as the caretaker of Guru Granth Sahib and this function may not be performed by any other person. It is kept covered in silken cloths, known as Rumala, to protect from heat, dust, pollution etc. It rests on a manji sahib under a rumala until brought out again
