The Bahá'í House of Worship in Delhi, India, popularly known as the Lotus Temple due to its flowerlike shape, is a Bahá'í House of Worship and also a prominent attraction in Delhi. It was completed in 1986 and serves as the Mother Temple of the Indian subcontinent. It has won numerous architectural awards. As with all other Bahá'í Houses of Worship, the Lotus Temple is open to all regardless of religion, or any other distinction, as emphasized in Bahá'í texts. The Bahá'í laws emphasize that the spirit of the House of Worship be that it is a gathering place where people of all religions may worship Godwithout denominational restrictions. The Bahá'í laws also stipulate that only the holy scriptures of the Bahá'í Faith and other religions can be read or chanted inside in any language; while readings and prayers can be set to music by choirs, no musical instruments can be played inside. Furthermore no sermons can be delivered, and there can be no ritualistic ceremonies practiced. All Bahá'í Houses of Worship, including the Lotus Temple, share certain architectural elements, some of which are specified by Bahá'í scripture.`Abdu'l-Bahá, the son of the founder of the religion, stipulated that an essential architectural character of a House of Worship is a nine-sided circular shape. While all current Bahá'í Houses of Worship have a dome, this is not regarded as an essential part of their architecture.
