शुक्लांबरधरो धीरो वाग्यतो नियमान्वितः । कृतसंध्याजपविधिः शिवपूजां समारभेत्
śuklāṃbaradharo dhīro vāgyato niyamānvitaḥ | kṛtasaṃdhyājapavidhiḥ śivapūjāṃ samārabhet
Clad in white garments, steady and restrained in speech, established in observances, and having duly completed Sandhyā and japa, one should begin the worship of Śiva.
Śāṇḍilya
Outer purity and inner restraint together make worship effective—discipline is itself a form of devotion.
No site is mentioned; the guidance is a general Śaiva pūjā standard.
Wear white, restrain speech, follow niyamas, complete Sandhyā and japa, then begin Śiva-pūjā.
