आज्ञासिद्धं क्रियासिद्धं श्रद्धासिद्धं सुमानसम् एवं च दक्षिणासिद्धं मन्त्रं सिद्धं यतस्ततः
ājñāsiddhaṃ kriyāsiddhaṃ śraddhāsiddhaṃ sumānasam evaṃ ca dakṣiṇāsiddhaṃ mantraṃ siddhaṃ yatastataḥ
A mantra is perfected when it is perfected by right injunction (ājñā), by correct performance (kriyā), by faith (śraddhā) and a well-composed mind; and likewise by the proper sacrificial fee (dakṣiṇā). Thus the mantra is established as effective in every way.
Suta Goswami (narrating the puranic teaching on worship discipline)
It defines mantra-siddhi for Linga-puja as a complete discipline: scriptural authorization, correct ritual action, faith with a purified mind, and proper dakṣiṇā—so worship is both inner (bhāva) and outer (vidhi).
Shiva as Pati responds to wholeness in sadhana: when the pashu (soul) aligns conduct, mind, and offering, the mantra becomes a true vehicle of Shiva’s grace, loosening pasha (bondage).
It highlights mantra-japa within Shiva-puja supported by śāstric vidhi, precise kriyā, śraddhā, mental purity (citta-śuddhi), and dakṣiṇā—key supports for effective Pāśupata-oriented worship.
