japa yaḥ puraścaraṇaṃ kṛtvā nityajāpī bhavennaraḥ tasya nāsti samo loke sa siddhaḥ siddhido vaśī
บุรุษผู้ทำปุรัศจะรณะของมนตร์ชปะให้ครบ แล้วเป็นผู้ชปะเป็นนิตย์ ย่อมไม่มีผู้เสมอในโลก เขาย่อมเป็นผู้สำเร็จ (สิทธะ) เป็นผู้ประทานสิทธิ และเป็นผู้ครองตนได้।
Suta Goswami (narrating the Purāṇic teaching on Śiva-mantra discipline)
It teaches that disciplined mantra-japa supported by puraścaraṇa makes the sādhaka spiritually powerful and steady, strengthening Śiva-upāsanā as a means to purify the pashu (individual soul) and loosen pāśa (bondage) through devotion to Pati (Śiva).
By emphasizing siddhi and mastery arising from Śiva-mantra, it implies Śiva as Pati—the source of grace and spiritual power—through whom the bound soul gains purification, inner sovereignty (vaśitva), and the capacity to bless others.
Puraścaraṇa with steady nitya-japa is highlighted—an applied sādhana aligned with Pāśupata-style discipline, aiming at mantra-siddhi, sense-control, and focused devotion to Mahādeva.
