nāradastu vasiṣṭhāya dadau devīmarundhatīm / ūrdhvaretāstatra muniḥ śāpād dakṣasya nāradaḥ
那罗陀（Nārada）将女神阿伦达蒂（Arundhatī）赐与婆悉吒（Vasiṣṭha）为妻。其后，这位牟尼成为“上行精力者”（ūrdhvareta），以节制清净而住；此事乃由达克沙（Dakṣa）对那罗陀所下之诅咒而起。

FAQs
Indirectly: by praising ūrdhvaretā (upward-conserved vital power), the verse points to the yogic discipline that steadies mind and prāṇa—conditions traditionally taught as supportive for realizing the Self beyond sensory desire.
The key term is ūrdhvaretā—continence/brahmacarya and sublimation of vital energy upward. In Yoga-śāstra and Purāṇic asceticism, this supports dhyāna (meditation), tapas (austerity), and inner steadiness.
This verse is primarily a ṛṣi-lineage and vow-of-continence passage; it does not directly address Śiva–Viṣṇu unity, but it aligns with the Kurma Purana’s broader synthesis by valuing yogic restraint as a shared ideal across Śaiva and Vaiṣṇava traditions.
