Valmiki Ramayana Ayodhya Kanda Sarga 63 Shloka 12

देवि Kausalya, इह in this world, सम्मोहात् out of delusion, बालेन like a boy, भक्षितम् eats, विषम् poison, यथा as, स्यात् may be, स्वयम् one's own self, कृतम् has been done, तत् इदम् that this, दुःखम् calamity, मे to me, अनुसंप्राप्तम् has befallen.

Just as a boy consumes poison out of delusion, O Devi, this sorrow has befallen me as a result of my own action.
