Valmiki Ramayana Aranya Kanda Sarga 60 Shloka 1

आव्रजमानस्य Rama was moving about, तस्य his, वामलोचनम् left eye, अधः underneath, भृशम् excessively, प्रास्फुरत् throbbed, रामः Rama, प्रास्खलच्च stumbled, अस्य his, वेपथुश्च shivering, जायत was produced.

As Rama was returning( to the hermitage), his left eye throbbed repeatedly and he stumbled and his body trembled. Rama's sorrow -- goes from tree to tree enquiring about Sita -- Rama and Lakshmana go in search of Sita.
