Valmiki Ramayana Aranya Kanda Sarga 71 Shloka 33

राघव Rama, त्रिषु in the three, लोकेषु worlds, तस्य for him, अविज्ञातम् unknown to him, नास्ति is not there, हि do, असौ he, पुरा in the past, कारणान्तरे for a different cause, सर्वान् all, लोकान् worlds, परिसृतः has roamed about.

O Rama, there is nothing that he does not know in the three worlds. In the past for a different reason he roamed all the (three) worlds. इत्यार्ष श्रीमद्रामायणे वाल्मीकीय आदिकाव्ये अरण्यकाण्डे एकसप्ततितमस्सर्गः।। Thus ends the seventyfirst sarga of Aranyakanda of the holy Ramayana the first epic composed by sage Valmiki.
