रामायण - युद्ध - दूत

यस्तु हित्वा मतं भर्तुः स्वमतं संप्रभाषते |
अनुक्तवादी दूतः सन् स दूतो वधमर्हति ||

- रामायण, युद्ध - दूत

It is a messenger's duty to stay true to his masters message (and intentions). Instead of that, if he conveys his own feelings, or tries to convey some thing never told by his master - then he deserves to be killed.

- Ramayana, Yuddha
