Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
तिलोत्तमाप्सराश्चैव देवी रम्भा मनोरमा ग्रामणीर् ऋतजिच्चैव सत्यजिच्च महाबलः //
tilottamāpsarāścaiva devī rambhā manoramā grāmaṇīr ṛtajiccaiva satyajicca mahābalaḥ //
Tilottamā, the apsaras; the divine Rambhā; the charming Manoramā; Grāmaṇī; and also Ṛtajit and Satyajit—heroes of great strength—are counted among those famed ones.
This verse is not about Pralaya; it functions as a catalogue of renowned celestial nymphs and mighty figures, typical of Purāṇic enumerations.
Indirectly, it preserves cultural memory: kings and householders are taught through Purāṇas to honor sacred history and exemplary figures; here, the emphasis is on remembering renowned names and epithets rather than prescribing duties.
No Vāstu/temple-building or ritual procedure is specified in this verse; it is primarily nominative (a list of notable beings).
