Matsya Purana — Soma
अतः परं प्रवक्ष्यामि पर्वणां संधयश्च याः यथा ग्रथ्नन्ति पर्वाणि आवृत्तादिक्षुवेणुवत् //
ataḥ paraṃ pravakṣyāmi parvaṇāṃ saṃdhayaśca yāḥ yathā grathnanti parvāṇi āvṛttādikṣuveṇuvat //
Now, further, I shall explain the joints and junctions of the structural segments (parvan)—how these segments are to be fastened together, like the linked nodes of a bamboo or sugarcane stalk as it turns and continues in successive sections.
This verse is not about Pralaya; it shifts into a technical Vastuvidya explanation, focusing on how structural parts are joined (saṃdhi) for continuity and stability.
It supports the king’s and householder’s dharma indirectly: commissioning safe, well-joined buildings and temples is a duty of proper governance and righteous household life, aligning public works and ritual spaces with śāstric standards.
It introduces rules for connecting building segments (parvan) through proper junctions (saṃdhi), using the bamboo/sugarcane node analogy to emphasize modular construction and secure interlinking in temple/building design.
