(a) It becomes easy for a devotee to concentrate in worshiping God in a temple where hundreds of devotees come for the same purpose. The God must be approached with humility, pridelessness, tolerance, simplicity, self-control, renunciation of the objects of sense gratification and steadiness. The environment of the temple produces a psychological effect, which helps in concentrating on the desired objective.
(b) A temple is the place where a devotee tries to remain free from the perception of evil of birth, death old age, disease and entanglement with children, wife, home and the rest of the world. The single purpose is to do worship and everything becomes unimportant.
(c) Ego is the greatest enemy of man, which is the cause of lust and anger. These evils are impediments in establishing a communion with God. In the environment of the temple in the midst of hundreds of other devotees, the false sense of ego begins to evaporate and the individual becomes a non-entity. This state is the best state for offering Puja to God. The body and mind remain in unison.
(d) It is said that God lies in faith. Temple is a place where people believe that God exists. It is the reason why God manifests Himself in temples for the sake of his devotee. Some temples attract large number of devotees and miracles and those temples are widely talked about.
(e) In India there is a tradition of pilgrimage of 4 dham - Badrinath, Dwarka, Puri and Rameshwaram. There are other important pilgrimage centers like Kedarnath, Kashi Vishwanath, Tirupati Balaji, Shirdi dham, Vaishno Devi, Amarnath and others. The devotees take all kinds of trouble to go to such distant places. The hardships make their will stronger and they march ahead with a clear focus.
(f) In the Indian tradition lakhs of people go to the Kumbh Mela for taking bath in holy rivers and offering worships at Haridwar, Prayag, Ujjain and Nasik. The Kumbh melas are the largest known human gatherings in the world where the individual identity of the devotees gets completely drowned in the sea of humanity. The devotees worship in a state of trance.
(g) Even in a neighborhood temple the environment for worship is different from the environment of the home because services of competent priests are available in the temple to guide devotees in perfuming rituals. The utensils utilized in worship are mainly of copper and brass, which are considered beneficial. The dimly lit Garbh Grih of the temple produces a sense of mystic and helps devotee focus on the divine. It also reminds that God is the only light amidst darkness.
