Account of the Birth/Origin of Vyāsa
रात्रौ व्यवायः कर्तव्यो न दिवेति श्रुतिर्जगौ । दिवासंगे महान्दोषो निन्दा चापि दुरासदा
rātrau vyavāyaḥ kartavyo na diveti śrutirjagau | divāsaṃge mahāndoṣo nindā cāpi durāsadā
The sacred teaching declares that conjugal union is to be undertaken at night and not in the daytime. For union by day brings a great fault, and it also invites blame that is hard to dispel.

It teaches discipline (niyama) within household life: even permitted desires should be regulated so the mind remains sattvic and fit for Shiva-bhakti and inward purity on the path toward liberation.
Linga-worship emphasizes purity, restraint, and consecrated living; by avoiding conduct deemed blameworthy, a devotee protects their ritual and mental purity, making daily Shiva-puja more effective and reverent.
The takeaway is sense-regulation and purity: keep a disciplined routine supportive of Shiva-sadhana—such as japa of the Panchakshara (Om Namaḥ Śivāya) and maintaining cleanliness before puja—rather than indulgence at improper times.
