Ekādaśāhna-vidhiḥ (The Rite Prescribed for the Eleventh Day): Maṇḍala-racanā, Āvāhana, Mudrā, and Ativāhika-devatā Pūjā
करिष्ये पार्वणं श्राद्धमिति संकल्प्य चोत्तरे । दद्याद्दर्भानुत्तमांश्च ह्यासनार्थं जलं स्पृशेत्
kariṣye pārvaṇaṃ śrāddhamiti saṃkalpya cottare | dadyāddarbhānuttamāṃśca hyāsanārthaṃ jalaṃ spṛśet
Facing north, one should make the resolve, “I shall perform the Pārvaṇa-śrāddha.” Then one should place excellent darbha-grass as seats, and touch water for purification and readiness to begin the rite.

It emphasizes saṅkalpa (clear inner resolve) and śuddhi (purification) as the foundation of dharmic action—outer ritual aligning the mind toward right intention, which in Shaiva understanding supports orderly life and prepares the seeker for Shiva-oriented discipline.
Though it describes śrāddha procedure, the same Shaiva principle applies to Saguna Shiva worship: begin with saṅkalpa and purification, establishing a sacred seat/space. Such ordered rites are considered supportive auxiliaries that steady the mind for devotion to Shiva.
Make a formal saṅkalpa facing north, arrange darbha as ritual seats, and perform ācamana/touching water for purification—an immediate takeaway for conducting śrāddha (and similarly for many Shiva Puja preliminaries).
