The symbols are models of the four most common types of sacred buildings: a Sikh temple, a Hindu temple, a mosque and a church. These typical forms are known in all religious traditions. Less known is that they refer to the human body.
Gurdawaras, the temples of the Sikhs, are dome-shaped, similar to the form of the head. The shape of the mosque reminds one of the fore-head. The nose-shaped towers of the churches often stand on a ground plan resembling a cross which corresponds to a person with outstretched arms.
Their message is: God is in us – the true temple is man himself.
