फलिष्यति न मे विद्या त्वद्वचश्चेति तत्तया अध्यापयिष्यामि च यं तस्य विद्या फलिष्यति //
phaliṣyati na me vidyā tvadvacaśceti tattayā adhyāpayiṣyāmi ca yaṃ tasya vidyā phaliṣyati //
“میری ودیا پھل نہیں دے گی—یہ تمہارا قول ہے۔” لہٰذا اسی عزم کے ساتھ میں اسی کو تعلیم دوں گا جس کی تم نشان دہی کرو گے؛ اس کی ودیا یقیناً بارآور ہوگی۔
This verse does not describe Pralaya directly; it emphasizes that knowledge becomes effective (phala-yukta) when taught in accordance with divine instruction—an ethical principle that can operate even in Pralaya-related narratives.
It frames a key duty: to obey righteous counsel and ensure knowledge is transmitted to a proper recipient. For a king (like Manu), governance includes preserving and propagating dharma-knowledge through qualified instruction.
No explicit Vastu or ritual procedure is stated; however, the verse supports the broader Matsya Purana principle that technical sciences (including Vastuvidya) yield results only when taught and applied under correct authority and method.
