शून्यमूलो ह्यस्य सुकरो भवति नैकदेशबलप्रयातः कृतपार्ष्णिप्रतिविधानः ॥ कZ_०७.१३.०६ ॥
śūnyamūlo hy asya sukaro bhavati naikadeśabalaprayātaḥ kṛtapārṣṇipratividhānaḥ
对这类出征者而言,其“根”(基地)将变为空虚,因而容易对付;但对仅率部分兵力出征、且已预先布置防范后袭者,则不然。

Do not empty the base by marching with everything unless rear-defense is secured; partial deployment with planned rear countermeasures can be safer.
