Ancient Hindu temples were chosen such that the location gave maximum positive benefits from magnetic and electric fields. Since devotees enter a temple barefoot, they benefit from the positive energy that enters the body through the feet. Another reason to enter barefoot is to keep impurities out of the sanctified atmosphere since footwear invariably picks up germs from the outside. All the five senses get activated in temples. The sense of hearing by the ringing of the temple bells. The sense of smell by the camphor used in the arti and essence
sticks as well as the flowers on the garlands. The arti lights up the dark interiors and activates the sense of sight as well as the sense of touch when the hands are lifted to touch the eyes. The sense of taste is activated by eating the prasad or drinking the water offered by the priest. In many temples the water is kept in copper or silver utensils and has tulsi leaves floating in it. The metal helps balance the three doshas of vata, kappa and pitta in the body. The tulsi leaves activate the taste buds apart from imparting other medical benefits of the tulsi plant. Finally, no temple visit is complete without #circumambulating the temple. This leads to further absorption of positive energies.
