भूम्येकान्तरं प्रकृतिमित्रं मातापितृसम्बद्धं सहजम् धनजीवितहेतोराश्रितं कृत्रिमम् ॥ कZ_०६.२.२० ॥
bhūmyekāntaraṃ prakṛtimitraṃ mātāpitṛsambaddhaṃ sahajam dhanajīvitahetorāśritaṃ kṛtrimam
A ‘natural ally’ (prakṛti-mitra) is one separated by intervening territory; an ‘inborn’ ally (sahaja) is linked through the mother’s or father’s line; an ‘artificial’ ally (kṛtrima) is one who seeks refuge/assistance for the sake of wealth or survival.
It guides reliability assessment: dynastic/embedded ties (sahaja) tend to be longer-horizon, while interest-driven ties (kṛtrima) require continuous incentives, monitoring, and contingency planning.
Because non-contiguity reduces immediate territorial rivalry, making cooperation more stable and less threatened by border friction.
