यस्य यद्विहितं कर्म तत्कुर्वन्मत्प्रियः सदा सन्ध्या संध्योपासनशीलः स्यात् सायं प्रातः प्रसन्नधीः

凡不怠慢而履行自身所规定之业者,恒为我所爱。应勤修桑迪亚(Sandhyā)与日之交界时的礼拜,于黄昏与黎明两时,保持心智澄明安宁。
Suta Goswami (narrating Shaiva dharma as taught within the Linga Purana’s discourse)
It grounds Linga-bhakti in śāstric discipline: by faithfully doing one’s prescribed nitya-karmas—especially Sandhyā-upāsanā—the devotee becomes “dear to Śiva,” making worship efficacious through purity and regularity.
Śiva is presented as Pati (the Lord) who responds to inner clarity and right conduct; devotion is not merely emotional but aligned with dharma that loosens pasha (bondage) by steadying the pashu (individual soul).
Sandhyā and Sandhyā-upāsanā—twilight worship at dawn and dusk—emphasizing prasanna-dhī (a serene intellect), a key support for Pāśupata-oriented purification and steadiness in practice.
