Matsya Purana — Division of Bhārata-varṣa
वर्षे किम्पुरुषे पुण्ये प्लक्षो मधुवहः स्मृतः तस्य किम्पुरुषाः सर्वे पिबन्तो रसमुत्तमम् //
varṣe kimpuruṣe puṇye plakṣo madhuvahaḥ smṛtaḥ tasya kimpuruṣāḥ sarve pibanto rasamuttamam //
In the holy land called Kimpuruṣa-varṣa, the plakṣa tree is remembered as “the honey-bearing” one; and all the Kimpuruṣas there drink its supreme, excellent sap.
This verse is not about Pralaya; it belongs to the cosmographic mapping of Jambūdvīpa, describing the distinctive sacred tree and nourishment (sap/“honey”) of Kimpuruṣa-varṣa.
Indirectly, it supports the Purāṇic ideal that righteous lands provide pure sustenance; for kings and householders, it echoes the duty to protect forests, sacred trees, and sources of nourishment so society can thrive in dharmic order.
No direct Vāstu or temple rule is stated; the ritual takeaway is ecological-sacral—certain regions are marked by sacred trees and their ‘rasa,’ implying offerings and reverence to such life-giving trees within Purāṇic practice.
