Udyoga-parva Adhyāya 64: Arjuna’s Instruction to Sanjaya
Message to the Kuru Assembly
वासुदेवो<पि दुर्धर्षो यतात्मा यत्र पाण्डव: | अविषटद्दां पृथिव्यापि तद् बल॑ यत्र केशव:
vāsudevo 'pi durdharṣo yatātmā yatra pāṇḍavaḥ | aviṣahyaṃ pṛthivyāpi tad balaṃ yatra keśavaḥ ||
毗度罗宣言：凡自制其心与诸根、不可征服的般度子阿周那所立之处，婆苏提婆（奎师那）亦同在；而凡有凯沙瓦亲自驻临之军，其冲击之势势不可当，强烈到连整个大地也难以承受其奔涌。

Educational Q&A
True power is not merely numerical or physical; it arises from self-mastery (yatātmā) allied with righteous counsel and divine presence (Kṛṣṇa). Such a combination makes a cause ethically and practically formidable.
In the Udyoga Parva’s pre-war counsel, Vidura warns about the strength on the Pāṇḍavas’ side: Arjuna’s disciplined heroism together with Kṛṣṇa’s presence makes their force irresistible, implying the folly of opposing them unjustly.
