Matsya Purana — Rite of Donating the ‘Sugar Mountain’
कृत्वा ताभ्याम् अशाठ्येन गुरुशुश्रूषणादिकम् सा च लीलावती वेश्याकालेन महतापि च //
kṛtvā tābhyām aśāṭhyena guruśuśrūṣaṇādikam sā ca līlāvatī veśyākālena mahatāpi ca //
Having performed with those two, without deceit, the duties beginning with sincere service to elders and teachers, she—Līlāvatī—also passed through a long span of life as a courtesan.
This verse does not address Pralaya; it focuses on ethical conduct—specifically sincere service (guruśuśrūṣā) and a biographical note about Līlāvatī’s life circumstance.
It highlights a core dharmic principle applicable to rulers and householders alike: duties should be performed without deceit (aśāṭhya), especially service and respect toward gurus/elders, which is treated as foundational to righteous life.
No Vāstu/temple-architecture or specific ritual procedure is mentioned; the key takeaway is moral discipline—truthful conduct and guru-service as a valued religious duty.
