Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
सर्गो यश्च प्रजानां तु संहारो यश्च तेषु वै अत ऊर्ध्वं प्रवक्ष्यामि शाल्मलस्य निबोधत //
sargo yaśca prajānāṃ tu saṃhāro yaśca teṣu vai ata ūrdhvaṃ pravakṣyāmi śālmalasya nibodhata //
Both the creation of beings and their dissolution as well—now, from this point onward, I shall explain the account of the Śālmalī tree; listen and understand.
It frames the teaching by explicitly pairing sarga (creation) and saṃhāra (dissolution), indicating that the coming topic is to be understood within the Purāṇic cycle of manifestation and withdrawal.
Indirectly, it models the dharma of attentive learning: Manu (the archetypal king) listens as cosmic principles are taught, implying that rulers and householders should ground conduct and decisions in śāstric instruction and cosmic order.
The verse functions as a transition into a technical exposition (likely relevant to sacred space symbolism or materials), signaling that the Śālmalī topic will be explained with doctrinal authority—useful for interpreting later Vastu/ritual prescriptions that rely on cosmological context.
