ईशानकल्पवृत्तान्तः तथा लैङ्गपुराणस्य संक्षेप-सूची
एरकास्त्रबलेनैव गमनं स्वेच्छयैव तु ब्रह्मणश्चैव मोक्षस्य विज्ञानं तु सुविस्तरम्
erakāstrabalenaiva gamanaṃ svecchayaiva tu brahmaṇaścaiva mokṣasya vijñānaṃ tu suvistaram
Самой силой Эракастры возможно движение по собственной воле; и также излагается во всей полноте высшее знание о Брахмане и об освобождении (мокше).
Suta Goswami (narrating to the sages of Naimisharanya)
It links outer means (powerful instruments/siddhi-symbols) with the inner culmination—vijñāna leading to mokṣa—implying that Linga-centered Shaiva practice must mature from ritual efficacy into liberating realization of Pati (Shiva) beyond bondage.
By pointing to Brahman-knowledge and mokṣa as the true ‘extensive teaching,’ it aligns with Shiva-tattva as Pati—the supreme reality whose realization dissolves pasha (bondage) for the pashu (soul); siddhis are secondary to liberation.
It hints at yogic siddhi (moving by will—icchā) as a byproduct of disciplined practice, while emphasizing that the Shaiva path (Pashupata-oriented) ultimately prioritizes vijñāna and mokṣa over mere powers.
