Ancient Hindus never built any temple just to please Gods. They were constructed based on the Vedic principles of building temples. The place for temple was selected on the availability of abundance of energy at that location.
Hindu temple reflects a synthesis of arts, the ideals of dharma, beliefs, values, and the way of life cherished under Hinduism.
Although it is not mandatory for a Hindu to visit a temple regularly, they play a vital role in Hindu society and culture. Hinduism is the world's third most popular religion, with around 900 million followers.One of the primary places where Hindus go to worship is a temple, which is known in Hinduism as a mandir.
Hindu Temples are epicentres of positive energy. The floor at the centre of the temple is a good conductor of these positive vibrations. And if you want to allow positive energy to pass through your feet to the body, you should not use footwear. Another reason is that shoes and chappals will have all the impurities as you use it everywhere. Hence they tend to spoil the pure environment of the temple.
Hinduism is the predominant religion of India. Hindus hold their religion very close to their heart. The word of their scripture is the word of the Lord to Hindus. Worshipping God idols of the Ultimate Reality and having faith in innumerable forms of the Supreme Power is an integral part of every Hindu's life.
Although there are atheists to be found in India yet the majority truly believe and abide by their holy scriptures. Many Hindu families have their own family patron deity known as the Kuldevta.
