Encyclopedic Reference: {"reference_type":"Procedure","entry_title":"Siddha/Su-siddha Mantra—Auspicious Opening and Closing","lookup_keywords":["siddha-ādi","śānta-siddha-anta","su-siddha","su-siddhānta","mantra-siddhi"],"quick_summary":"A mantra framed with ‘siddha’ at the start and ‘śānta-siddha’ at the end is said to yield immediate accomplishment; similarly, ‘su-siddha … su-siddhānta’ is to be treated as a pre-perfected (siddha) mantra for efficacy."}
Concept: Śabda-śakti and siddha-bhāva: deliberate mantra-framing and the assumption of accomplishedness as a sādhanā-auxiliary.
Application: During japa/nyāsa, begin and end with the prescribed siddha-markers and maintain the mental stance that the mantra is already siddha (niścaya), avoiding doubt.

FAQs
It gives a technical rule of mantra-śāstra: certain mantras are considered instantly efficacious when framed with specific ‘siddha/su-siddha’ beginnings and ‘śānta-siddha/su-siddhānta’ concluding formulas, and are to be treated as siddha (already perfected) in use.
Beyond mythology, the Agni Purāṇa preserves practical, system-like instructions on mantra composition and ritual efficacy—one of its many technical domains alongside architecture, polity, medicine, and literary theory.
By prescribing ‘śānti’ (pacification) and ‘siddhi’ (attainment) as formal mantra-components, the verse frames mantra practice as a means to remove obstacles and stabilize spiritual results, aiming at swift success with controlled, auspicious intent.
