Prana pratishtha is performed at the time of installing the deity, or at the time of renovation (when a deity is removed and then replaced some time later). The ritual consumes a large amount of money and requires about four months of religious observance.
It is performed by a puja-sadhaka within the premises of the temple whom the temple priests (sadhakas) (a) propose for the task; (b) if the puja-sadhaka agrees, is circumambulated under the guidance of a guru, who is in turn circumambulated numerous times by the puja-sadhaka.
The puja-sadhaka takes the three articles in which the deity is to be installed/retired: the deity, its urn (jangala), and the main altar; and places them in a safe place, such as under a special stone or in a secret space. Sometimes, a lock or padlock or a strong iron chain is placed over the urn to prevent theft. In the ordinary course of the ceremonial, the puja-sadhaka is to be under the protection and auspices of the guru and is permitted to wear a deity of his deva or of his choice. Before starting the puja-sadhaka begins the recitation of a hymn to the deity (the Garbhadasa stotra), as follows: d2c66b5586
