The Golden Temple, located in the city of Amritsar in the state of Punjab,is a place of great beauty and sublime peacefulness. Originally a small lake in the midst of a quiet forest, the site has been a meditation retreat for wandering mendicants and sages since deep antiquity. The Buddha is known to have spent time at this place in contemplation.Two thousand years after Buddha's time, another philosopher-saint came to live and meditate by the peaceful lake. This was Guru Nanak (1469-1539), the founder of the Sikh religion. After the passing away of Guru Nanak, his disciples continued to frequent the site; over the centuries it became the primary sacred shrine of the Sikhs. The lake was enlarged and structurally contained during the leadership of the fourth Sikh Guru (Ram Dass, 1574-1581), and during the leadership of the fifth Guru (Arjan, 1581-1606), the Hari Mandir, or Temple of God was built. From the early 1600s to the mid 1700s the sixth through tenth Sikh Gurus were constantly involved in defending both their religion and their temple against Muslim armies. On numerous occasions the temple was destroyed by the Muslims, and each time was rebuilt more beautifully by the Sikhs. From 1767 onwards, the Sikhs became strong enough militarily to repulse invaders. Peace returned to the Hari Mandir.
