Shivamurti–Pratishtha Phala: Shivalaya-Nirmana, Kshetra-Mahatmya, Tirtha-Snana, and Mandala-Vidhi
गङ्गास्नानसमं पुण्यं लभते नात्र संशयः अस्तं गते तथा चार्के स्नात्वा गच्छेच्छिवं पदम्
gaṅgāsnānasamaṃ puṇyaṃ labhate nātra saṃśayaḥ astaṃ gate tathā cārke snātvā gacchecchivaṃ padam
He attains merit equal to bathing in the Gaṅgā—of this there is no doubt. When the Sun has set, having bathed with devotion, one proceeds to Śiva’s state (Śiva-pada), the supreme abode of the Pati who liberates the paśu from bondage.
Suta Goswami (narrating the tirtha/vrata teaching within the Linga Purana discourse)
It equates a prescribed purificatory bath with the famed merit of Gaṅgā-snāna and frames purification as a direct support to devotion toward Śiva, culminating in ‘Śiva-pada’—the spiritual goal of Shaiva practice.
Śiva is implied as the supreme ‘pada’ (state/abode) and as Pati—the Lord who grants the highest attainment beyond worldly merit, freeing the paśu from pasha through grace supported by right conduct.
Ablution (snāna), specifically connected with the time of sunset (astaṁ gate), is highlighted as a Shaiva purification rite that prepares the practitioner for devotion and liberation-oriented practice.
