Ramayana 2.18.41

इतीव तस्यां परुषं वदन्त्यांन चैव रामः प्रविवेश शोकम्।प्रविव्यथे चापि महानुभावोराजा तु पुत्रव्यसनाभितप्तः।।।।

itīva tasyāṁ paruṣaṁ vadantyāṁ na caiva rāmaḥ praviveśa śokam | pravivyathe cāpi mahānubhāvo rājā tu putravyasanābhitaptaḥ ||

Even as she spoke such harsh words, Rāma did not sink into sorrow. But the noble king—scorched by the calamity befalling his son—was wracked with pain.
