婆悉吒说道：“确然，他们将以此同一形态繁衍众生；并自劫初至劫终——直至大毁灭（pralaya）——恒自安住于所命之界限之内，守持宇宙秩序，亦守其本分。”

Educational Q&A
That the agents of creation (implicitly the Prajāpati-like progenitors) not only generate beings but also remain steadfast within ordained limits across the entire cycle of time—modeling dharma as stability, restraint, and maintenance of cosmic order from yuga-beginning to pralaya.
Vasiṣṭha is describing how certain primordial/progenitor beings will continue the work of creation in the same form and will preserve their proper station and boundaries throughout the full span of an age, indicating continuity of governance and order in the cosmos.
