Matsya Purana — Characteristics of Dvāpara and Kali Yugas
तदेव च तदन्यासु पुनस्तद्वै यथाक्रमम् सर्गे सर्गे यथा भेदा ह्य् उत्पद्यन्ते तथैव च //
tadeva ca tadanyāsu punastadvai yathākramam sarge sarge yathā bhedā hy utpadyante tathaiva ca //
And that very same process occurs again in the others as well, indeed in due order; in each cycle of creation, the distinctions and varieties arise exactly as they do each time.
It teaches cyclical cosmology: after dissolution, creation happens again in an ordered sequence, and the same kinds of distinctions (bheda) reappear in each new sarga.
By stressing that the world’s order repeatedly manifests “according to sequence,” it supports dharma as alignment with cosmic order—encouraging kings and householders to uphold stable, rule-based conduct rather than arbitrary action.
No direct Vāstu or ritual rule is stated, but the principle of yathākramam (proper sequence) underlies correct ritual procedure and traditional building canons—work proceeds by fixed stages so the intended forms and distinctions manifest properly.
