Harmandir Sahib, popularly known as the Golden Temple is the most important Sikh Shrine and has emerged as a spiritual capital of the Sikh faith. Because of its unique role in Sikh society and psyche it has become the symbol of the Sikh community's undying faith and religious fervor. The temple was designed by the fifth Sikh Guru Arjan Dev who chose to provide four doors to the temple, one in each direction signifying its accessibility to people from all four directions of the world, irrespective of their caste or creed. The Guru invited a well known Sufi Saint, Mian Mir of Lahore to lay the foundation of the Golden Temple. The construction of the sacred pool and the temple was carried out by voluntary labour and cash contributions from devotees from far and near. When Ranjit Singh became the Maharaja of Panjab, he commissioned well knowed artisans and craftsmen who decorated the temple with stone inlay work as well as beautiful floral patterns and covered the temple with gold-plated copper sheets. From then on it became to be known as the Golden Temple. This perhaps is the only temple in the world which was designed by the founder in such a way where the sanctum sanctorum floats like a lotus is a sacred pool.
