Matsya Purana — Code of Conduct and Vow-Procedure for Courtesans
करोति याशेषमखण्डमेतत् कल्याणिनी माधवलोकसंस्था सा पूजिता देवगणैर् अशेषैर् आनन्दकृत्स्थानम् उपैति विष्णोः //
karoti yāśeṣamakhaṇḍametat kalyāṇinī mādhavalokasaṃsthā sā pūjitā devagaṇair aśeṣair ānandakṛtsthānam upaiti viṣṇoḥ //
She—auspicious and established in Mādhava’s (Vishnu’s) world—brings this whole merit to completion without remainder; and, being worshipped by all the hosts of gods, she attains Vishnu’s abode, the realm that bestows bliss.
This verse is not about pralaya; it is a phala-śruti style statement emphasizing the post-mortem spiritual destination—attaining Vishnu’s bliss-giving abode—through completed merit and devotion.
It frames dharmic life as culminating in “akhaṇḍa” (unbroken) merit: a king or householder who sustains consistent worship, vows, charity, and temple/service-oriented piety is promised a higher devotional end—entry into Vishnu’s realm.
No direct Vāstu or iconographic rule is stated; the ritual takeaway is completion and integrity of observance (akhaṇḍa) and the devotional result—honour by the gods and attainment of Vishnu’s ānanda-kṛt-sthāna.
