Matsya Purana — Saubhagya-Śayana Vow: Lalitā/Gaurī–Śiva Worship
विकारवच्च गोक्षीरं कुसुम्भं कुङ्कुमं तथा लवणं चाष्टमं तद्वत् सौभाग्याष्टकमुच्यते //
vikāravacca gokṣīraṃ kusumbhaṃ kuṅkumaṃ tathā lavaṇaṃ cāṣṭamaṃ tadvat saubhāgyāṣṭakamucyate //
Likewise, (one should take) curd and cow’s milk, safflower and saffron; and salt as the eighth—thus is the “Eightfold Auspicious Set” (Saubhāgya-aṣṭaka) spoken of.
This verse is not about Pralaya; it defines auspicious ritual substances (Saubhāgya-aṣṭaka) used for prosperity-oriented observances.
It supports gṛhastha-dharma by prescribing recognized auspicious materials for rites (vrata/pujā), reflecting orderly, dharmic maintenance of prosperity and wellbeing in the household and realm.
Ritually, it enumerates items commonly used in auspicious applications—milk/curd for purification and offering, kusumbha/kuṅkuma for auspicious marking, and salt as a protective/complete-the-set substance—together forming the Saubhāgya-aṣṭaka.
