There are eight cities, each of which measures 2500 square yojanas in extent. In the centre of Mahameru is Brahma\’s city called Manovati and to the east of Manovati is Indra\’s city Amaravati. Other cities belong to Agni, Nirrti, Varuna, Vayu, Kubera and Shiva.” Amaravati conveys the idea of an eternal city, but according to the Adi Granth all the gods and goddesses will ultimately pass away, therefore the concept of \’Eternal City\’ with regard to Indra cannot hold good.
The concept of Amarapuri with regard to the Lord-God, who is Immortal and Eternal, propounded by the Sikh Gurus and the Radical Saints in the sense of \’An Eternal City\’ is virtually justifiable. Other names of such a city mentioned in the Sikh Scripture are \’Abichal Nagar\’ (Everlasting City) p. 785 and \’Begumpura\’ (The City of Bliss) p. 345.
