Mother Sita said: 'O brother, the one who has poured this delightful tale like nectar into my ears — why does he not reveal himself?' Shree Hanuman then came near. Mother Sita turned and sat facing him, and a great wonder arose in her heart.
माता सीता बोलीं — 'हे भाई! जिसने कानों में अमृत की तरह मीठी यह कथा सुनाई, वह प्रकट क्यों नहीं होता?' तब श्री हनुमान् जी पास चले आए। माता पलट कर बैठ गईं — मन में बड़ा विस्मय हुआ।
