99 - అథ సూర్య ప్రతిష్టా విధానమ్.

Summary of chapter 99 of the Agni Purāṇa is as follows:

The ninety-ninth chapter presents the installation procedure for the image of Bhagavān Sūrya. The standard template of maṇḍapa construction, snāna, and preliminary rites is applied, but the specific threefold tattva nyāsa (ātma, vidyā, śiva) in the image uses the ĀkāśĀdi pañcabūta (the five elements beginning with ākāśa) as the theological framework rather than the purely Śaiva kalā framework. The pīṭha is purified and consecrated using the sarvatomukhī (all-faced) śakti mantra. The guru installs Sūrya using his specific mantra while visualizing the deity's blazing form, and the name of Sūrya's attendant deities is given the suffix "svāmin" or "pāda" to complete the mantra form. The chapter's brevity reflects that Sūrya installation follows the same general procedures already described — the chapter serves primarily to specify the Sūrya-specific variations rather than to repeat the entire protocol.
