Shivamurti–Pratishtha Phala: Shivalaya-Nirmana, Kshetra-Mahatmya, Tirtha-Snana, and Mandala-Vidhi
कर्म कुर्याद्यदि सुखं लब्ध्वा चापि प्रमोदते तस्माद् आयतनं भक्त्या यः कुर्यान् मुनिसत्तमाः
karma kuryādyadi sukhaṃ labdhvā cāpi pramodate tasmād āyatanaṃ bhaktyā yaḥ kuryān munisattamāḥ
Если человек совершает деяния и, обретя счастье, радуется ему, то потому, о лучшие из мудрецов, следует с бхакти воздвигнуть аятану — священную обитель — для Владыки (Шивы).
Suta Goswami (narrating to the sages at Naimisharanya)
It directs devotees to convert worldly enjoyment into sacred merit by establishing an āyatana—an abode/shrine for Shiva—thereby grounding happiness in bhakti-centered Linga worship.
Shiva is implied as Pati (the Lord) worthy of a consecrated seat; devotion to Him reorients the pashu’s (individual soul’s) karma away from mere pleasure and toward a sanctified relationship with the Lord.
A temple/shrine-making and installation impulse (āyatana-karaṇa) as a devotional act—supporting Linga-puja and aligning karma with Pashupata-oriented discipline through bhakti.
