Matsya Purana — Hiranyakashipu’s Boons
मन्दारकुन्दलक्ताश्च पतङ्गाः कुटजास्तथा रक्ताः कुरण्टकाश्चैव नीलाश्चागरुभिः सह //
mandārakundalaktāśca pataṅgāḥ kuṭajāstathā raktāḥ kuraṇṭakāścaiva nīlāścāgarubhiḥ saha //
Also (there should be) mandāra, kunda, and laktā plants; likewise pataṅga and kuṭaja; red kuraṇṭaka flowers as well, and blue varieties—together with agaru (aloeswood) trees.
This verse does not address Pralaya; it gives a practical list of auspicious and fragrant plants recommended for cultivated spaces such as gardens or sacred precincts.
It supports the dharma of maintaining orderly, auspicious surroundings—kings and householders are encouraged to establish gardens with fragrant, flowering, and beneficial plants as part of public welfare, beauty, and religious merit.
In Vastu-oriented planning, planting specific flowers and aromatic trees (like agaru) is part of designing temple environs and pleasure-gardens, enhancing sanctity, fragrance, and auspiciousness around built spaces.
