कृतमायतनं दद्यात्क्रमाच्छतगुणं फलम् । कलशं तत्र चारोप्य एकविंशत्कुलैर्युतः
kṛtamāyatanaṃ dadyātkramācchataguṇaṃ phalam | kalaśaṃ tatra cāropya ekaviṃśatkulairyutaḥ
Wenn man ein vollendetes Heiligtum (āyatana) spendet, vermehrt sich die Frucht der Tat der rechten Ordnung gemäß hundertfach. Und setzt man darauf den Kalaśa, das Weihegefäß, so ist man mit einundzwanzig Geschlechtern verbunden und teilt ihren Segen.
Lomaharṣaṇa Sūta (deduced: Māheśvarakhaṇḍa narrative frame)
Listener: Mahāsena (Skanda)
Scene: A donor offers a newly completed stone shrine to Śiva; artisans place a shining golden kalaśa atop the śikhara; a subtle aura links the donor to a chain of 21 ancestors/descendants.
Building and gifting sacred infrastructure for Śiva is praised as a massively amplifying act of dharma with wide-reaching familial merit.
No particular tīrtha is specified; the teaching applies broadly to Śaiva temple-building and consecration.
Dāna of a completed āyatana (shrine) and placing a kalaśa (consecration pot) upon it.
