वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
छाया स्वपुत्राभ्यधिकं स्नेहं चक्रे मनौ तदा पूर्वो मनुर्न चक्षाम यमस्तु क्रोधमूर्छितः
chāyā svaputrābhyadhikaṃ snehaṃ cakre manau tadā pūrvo manurna cakṣāma yamastu krodhamūrchitaḥ
Then Chāyā showed to Manu an affection exceeding even that for her own sons. The former Manu did not perceive the truth, while Yama, overcome by wrath, became bewildered.
Suta Goswami (narrating to the sages at Naimisharanya)
It highlights inner purity as essential for Shiva-bhakti: partiality and anger act as pasha (bondage) that clouds discernment, whereas Linga-puja aims at cleansing the pashu (soul) so it can turn toward Pati (Shiva) with steadiness.
Indirectly, it contrasts human delusion and wrath with the Shaiva ideal: Shiva-tattva is the clarifying Pati-principle that dissolves moha and krodha; when the pashu is ruled by these, it fails to see truth.
A practical Pashupata-Yogic takeaway is krodha-nigraha (restraint of anger) and viveka (discernment), disciplines that support effective Shiva-puja and steady meditation on the Linga.
