Matsya Purana — Manifestation of Kauśikī
भविष्यसि न मद्द्वाःस्थो वर्षपूगान्यनेकशः अतस्ते ऽत्र न दास्यामि प्रवेशं गम्यतां द्रुतम् //
bhaviṣyasi na maddvāḥstho varṣapūgānyanekaśaḥ ataste 'tra na dāsyāmi praveśaṃ gamyatāṃ drutam //
For countless multitudes of years you shall not remain at my threshold. Therefore I will not grant you entry here—go away quickly.
It reflects the Pralaya-era theme of divine refuge and selection: not everyone is admitted to the divine “threshold,” implying moral or karmic criteria operating during catastrophic transition.
It underscores accountability: access to protection or grace is not automatic. A king or householder must uphold dharma consistently, not merely seek shelter at the last moment.
The key term is “dvāḥstha” (standing at the door/threshold), a liminal ritual-architectural idea: thresholds mark eligibility and controlled entry, echoing broader Purāṇic notions of regulated access to sacred spaces.
