Matsya Purana — The Greatness of the Vibhūti-Dvādaśī Vow: Pushkara
कल्पादौ सप्तमं द्वीपं तस्य पुष्करवासिनः लोके च पूजितं यस्मात् पुष्करद्वीपमुच्यते //
kalpādau saptamaṃ dvīpaṃ tasya puṣkaravāsinaḥ loke ca pūjitaṃ yasmāt puṣkaradvīpamucyate //
At the beginning of the aeon (kalpa), the seventh continent came into being. Its inhabitants are the Puṣkaravāsins; and because it is revered in the world, it is called Puṣkara-dvīpa (the Continent of Puṣkara).
It situates Puṣkara-dvīpa within kalpa-time (the beginning of an aeon), emphasizing cosmic ordering rather than describing a pralaya event.
Indirectly, it supports the Purāṇic ideal that rulers and householders should honor sacred places and uphold reverence for divinely ordered geography—cultivating dharma through respect for what is “pūjita” (venerated).
No direct Vāstu or temple rule appears here; the key ritual takeaway is the notion of a region being “pūjita” (worthy of worship), which underlies pilgrimage, place-sanctity, and site selection in later ritual practice.
