Madhu–Kaiṭabha, Nārāyaṇa’s Yoga-Nidrā, Rudra’s Manifestation, and the Aṣṭamūrti–Trimūrti Teaching
ततः प्रभृति देवो ऽसौ न प्रसूते ऽशुभाः प्रजाः / स्वात्मजैरेव तै रुद्रैर्निवृत्तात्मा ह्यतिष्ठत / स्थाणुत्वं तेन तस्यासीद् देवदेवस्य शूलिनः
tataḥ prabhṛti devo 'sau na prasūte 'śubhāḥ prajāḥ / svātmajaireva tai rudrairnivṛttātmā hyatiṣṭhata / sthāṇutvaṃ tena tasyāsīd devadevasya śūlinaḥ
それ以来、その神は不吉なる生類をもはや生み出さなかった。自らの精髄より生じたそのルドラたちと共に、心を外なる創造から退け、内なる制御に安住して留まった。ゆえに、三叉戟を執る देवदेव（神々の神）は「スターヌ（Sthāṇu）」—「堅固にして不動なる者」—と称されるに至った。

FAQs
It presents divinity as capable of nivṛtti—withdrawal from outward projection—signifying inner steadiness (sthāṇutva). The divine ‘self’ is not compelled by creation; it can rest established in itself.
The key yogic cue is nivṛtta-ātmā—turning the mind inward from pravṛtti (outgoing activity) to steadiness. This aligns with Pāśupata-flavored discipline: restraint, inner establishment, and cessation of impure tendencies.
While explicitly about Rudra/Śiva, the Kurma Purana’s broader frame treats such divine functions (creation/withdrawal) as expressions of one supreme governance—supporting a Shaiva–Vaishnava synthesis rather than sectarian opposition.
