अव्यक्तमाहु: प्रकृतिं परां प्रकृतिवादिन: । तस्मान्महत् समुत्पन्नं द्वितीयं राजसत्तम,नृपश्रेष्ठ! प्रकृतिवादी विद्वान् मूल प्रकृतिको अव्यक्त कहते हैं। उससे दूसरा तत्त्व प्रकट हुआ, जिसे महत्तत्त्व कहते हैं
avyaktam āhuḥ prakṛtiṁ parāṁ prakṛtivādinaḥ | tasmān mahat samutpannaṁ dvitīyaṁ rājasattama, nṛpaśreṣṭha |
Vasiṣṭha said: “The exponents of Prakṛti declare the supreme Prakṛti to be the Unmanifest. From that Unmanifest there arises the second principle, the Great (Mahat). O best of kings, O foremost of rulers, this is how the knowers of Prakṛti describe the origin of the first evolute.”
वसिष्ठ उवाच
The verse presents a Prakṛti-based cosmology: the highest Prakṛti is called the Unmanifest (avyakta), and from it emerges the next principle, Mahat (the Great), which functions as the first manifest evolute and a foundation for further creation.
In Śānti Parva’s philosophical instruction, Vasiṣṭha addresses a king and explains a doctrinal account of creation used by Prakṛti-theorists, identifying the Unmanifest as the source and Mahat as the subsequent principle that arises from it.
