Shloka 14
तस्माद् विश्वसितव्यं च विग्रहं च समाचरेत् । देशं कालं॑ च विज्ञाय कार्याकार्यविनिश्षये,अतः देश-कालको समझकर कर्तव्य-अकर्तव्यका निश्चय करके किसीपर विश्वास और किसीके साथ युद्ध करना चाहिये
tasmād viśvasitavyaṃ ca vigrahaṃ ca samācaret | deśaṃ kālaṃ ca vijñāya kāryākārya-viniścaye ||
Therefore, one should know when to place trust and when to enter into conflict. Having understood the place and the time, one must determine what ought to be done and what ought not to be done; on that basis, one should either rely on another or oppose them as the situation demands.

Educational Q&A
Bhishma teaches contextual ethics: decisions about trusting others or engaging in conflict should be made only after judging deśa (place/circumstances) and kāla (time/occasion), and clearly discerning kārya (right action) versus akārya (wrong action).
In the Shanti Parva’s instruction on conduct and governance, Bhishma is laying down a practical rule for rulers and householders alike: do not act from impulse—first assess circumstances, then decide whether conciliation/trust or opposition/war best serves dharma and the intended goal.
