เมื่อจำแนกได้ว่าเป็น ‘สิทธะ’, ‘สาธยะ’, ‘สุ-สิทธะ’ และ ‘อะริ’ แล้ว พึงคำนวณตามลำดับ ครั้นนำไปวางไว้ทั้งต้นและท้ายของมนตร์ มนตร์นั้นย่อมเป็นผู้ประทานความสำเร็จ ให้ผลทวีคูณถึงร้อยเท่า

The intended outcome is intensified siddhi, described as hundredfold."}
Concept: Mantra is treated as a system with measurable states; correct gaṇanā and placement (ādi/anta) are upāyas to remove ‘ari’ (obstruction) and stabilize siddhi.
Application: Diagnose the mantra’s category via the taught gaṇanā method (as given in the surrounding section) and apply the prescribed framing to strengthen practice outcomes.

Sandhi Resolution Notes: सुशिद्धो 'रिः = सु-सिद्धः अरिः (विसर्ग-लोपः/अवग्रहः)। मन्त्रस्यादौ = मन्त्रस्य आदौ। चान्ते = च अन्ते। स्याच्छतांशतः = स्यात् शतांशतः (त् + श → च्छ)।

It teaches a mantra-prayoga: classify/compute the mantra’s operative status (siddha, sādhya, su-siddha, ari) and, by placing the computed element(s) at the beginning and end of the mantra, intensify the mantra’s effectiveness.
Beyond mythology, it preserves procedural mantra-shastra—categorization, calculation, and practical deployment rules—showing the Agni Purana as a compendium of applied religious-technical knowledge.
By correctly structuring and empowering the mantra, the practitioner reduces obstacles (ari) and increases siddhi, aiming at faster fruition of intended spiritual or ritual goals through disciplined method.
