Above the Baha'i House of Worship (Mashriqu'l-Adhkár), New Delhi, India.
Baha'i temples are open to the people of all religions.
A fundamental belief of Baha'is is that all religions emerge from and flow from the same eternal Source, and that "religion" as we call it has been a progressive process over millennia - that through untold numbers of spiritual teachers civilizations have gradually come to understand Man's connection to his Creator. Baha'is believe that science and religion, freed from superstition and error, reveal this same Source in different, complimentary ways.
Baha'u'llah, the founder said that religion must be the cause of love and the advancement of mankind, otherwise it would be better to walk away from it.
The Baha'i Faith is an Iranian-origin religion that claims a connection to all the religions of mankind, and proclaims that the time we're living in now, is the Day of Days anticipated by prophets, mystics and poets - the time for the entire human race to reach its maturity, that will witness the permanent cessation of warfare and prejudice, and the global, golden civilization of unending progress.
