उपायधर्म-सेनायोगः
Upāya-dharma and Senāyoga: Expedient Ethics & Army Deployment
अभिनीतानि शस्त्राणि योधाश्व कृतनिश्चया: । चैत्र्यां वा मार्गशीर्ष्या वा सेनायोग: प्रशस्यते
abhinītāni śastrāṇi yodhāś ca kṛtaniścayāḥ | caitryāṃ vā mārgaśīrṣyāṃ vā senāyogaḥ praśasyate ||
毗湿摩说道：“当兵器已妥善备办，战士亦已立下与敌交锋之坚决之志，则军队于凯特罗月（Caitra）或摩尔伽希尔沙月（Mārgaśīrṣa）的望日（满月）出征，被视为吉祥而可称道。”

Educational Q&A
Bhīṣma links ethical statecraft with practical readiness: war should not be undertaken impulsively; only when arms are prepared and soldiers are resolute, and even then one should observe traditionally auspicious timing for mobilization.
In Śānti Parva’s instruction on governance and conduct, Bhīṣma gives Yudhiṣṭhira pragmatic counsel about military organization, recommending specific full-moon times (Caitra or Mārgaśīrṣa) for an army’s departure once preparations and resolve are complete.
