Hinduism
A Hindu temple is a house of god(s). It is a space and structure designed to bring human beings and gods together, infused with symbolism to express the ideas and beliefs of Hinduism. A temple incorporates all elements of Hindu cosmology, the highest spire or dome representing Mount Meru – reminder of the abode of Brahma and the center of spiritual universe, the carvings and iconography symbolically presenting dharma, kama, artha, moksha and karma. The layout, the motifs, the plan and the building process recite ancient rituals, geometric symbolisms, and reflect beliefs and values innate within various schools of Hinduism. Hindu temples are spiritual destinations for many Hindus (not all), as well as landmarks for arts, annual festivals, rite of passage rituals, and community celebrations.
Hindu temples come in many styles, diverse locations, deploy different construction methods and are adapted to different deities and regional beliefs. Two major styles of Hindu temples include the Gopuram style found in south India, and Nagara style found in north India. Other styles include cave, forest and mountain temples. Yet, despite their differences, almost all Hindu temples share certain common architectural principles, core ideas, symbolism and themes.
Islam and other religions
In the introduction to his "Indica", Biruni himself writes that his intent behind the work was to engage dialogue between Islam and the Indian religions, particularly Hinduism as well as Buddhism. Biruni was aware that statements about a religion would be open to criticism by its adherents, and insisted that a scholar should follow the requirements of a strictly scientific method. According to William Montgomery Watt, Biruni "is admirably objective and unprejudiced in his presentation of facts" but "selects facts in such a way that he makes a strong case for holding that there is a certain unity in the religious experience of the peoples he considers, even though he does not appear to formulate this view explicitly." Biruni argued that Hinduism was a monotheistic faith like Islam, and in order to justify this assertion, he quotes Hindu texts and argues that the worship of idols is "exclusively a characteristic of the common people, with which the educated have nothing to do."
