Nṛga-upākhyāna: Brāhmaṇa-sva and the Consequence of Misappropriated Gift-Cattle (कृकलास-रूपे नृगोपाख्यानम्)
अटवीपर्वताश्रैव नद्यस्तीर्थानि यानि च
aṭavī-parvatāś caiva nadyas tīrthāni yāni ca
毗湿摩说道：“森林与群山，以及其间的江河与圣渡（tīrtha），并不隶属于任何一位私有之主；众人皆视之为公有。故在此等处行施罗陀（śrāddha），无须购地。噫，民之主啊，如是便已宣说布施土地之果报。”

Educational Q&A
Bhishma teaches that certain natural and sacred spaces—forests, mountains, rivers, and tīrthas—are not private property; hence one need not buy land to perform śrāddha there. The point supports dharmic giving and correct ritual conduct without unnecessary acquisition.
In Anuśāsana Parva, Bhishma continues instructing Yudhiṣṭhira on dharma, especially gifts and rites. Here he clarifies where śrāddha may be performed and links it to the discussion of the merit (phala) of land-gift (bhūmi-dāna).
