7.17.8

śapathātikrame mahatāṃ tapasvināṃ mukhyānāṃ vā prātibhāvyabandhaḥ pratibhūḥ //

In order to avoid the contingency of violation of oath, peace made with the security of such persons as ascetics engaged in penance, or nobles is peace with a security. In such a peace, whoever takes as security a person capable of controlling the enemy gains more advantages, while he who acts to the contrary is deceived.
