People who have faith have always needed a place of worship throughout history. Places of worship are where doctrines have been taught to the people and formal obligations have been fulfilled and are indispensable worldly elements of almost all religions, which direct people’s relations with both God and each other, as well as with other beings. Therefore, these sacred places have played a crucial role in starting communication between people. Thanks to such communication, those people who have known and bonded with each other, who have found solutions for their own problems, or who have taken a common stand, have considered such places as the safest centers as well. Some took refuge in temples to save their own lives, and some saints, who have broken off connections to people or the world, settled in temples to believe in the first step of happiness (nirvana), as well as some wealthy people who regarded temples as a place that they could deposit their wealth or gold. In this context, the theory that modern banking procedures emerged in temples seems not frail at all.
