अलंकृत्य सुवेषं च गंधस्रग्वस्त्रभूषणैः । पुण्याहं वाचयित्वा च ब्राह्मणानभिपूज्य च । समुद्रतीरे नद्यां च गोष्ठे देवालये ऽपि वा । शुचौ देशे गृहे वापि काले सिद्धिकरे तिथौ

当自我庄严：衣着端正，涂香，佩花鬘，着净衣与饰物；并令诵读吉祥仪式“普尼亚哈”（puṇyāha），如法敬奉婆罗门。随后，于海滨、河畔、牛舍、或神庙之中——乃至任何清净之处，即便在家——在有利于成就的时辰与月日（tithi）上，应当开始对湿婆的礼拜，以求灵性成办。

FAQs
It teaches that outer purity (clean dress, fragrance, orderly conduct) and inner sanctity (honoring brāhmaṇas, choosing a pure place and auspicious time) support focused Śiva-upāsanā, helping the devotee progress toward siddhi and ultimately liberation under Pati (Śiva).
The verse frames the proper setting for Saguna Śiva worship—typically centered on the Śiva-liṅga—showing that liṅga-pūjā can be performed not only in temples but also at home or other pure locations when done with reverence, purity, and right observances.
It suggests preparatory observances: personal adornment and cleanliness, arranging a puṇyāha recitation, honoring brāhmaṇas, and selecting a pure place and auspicious tithi—then commencing Śiva-pūjā (often with mantra-japa such as the Pañcākṣarī, if prescribed in the surrounding context).
