Ramayana
इत्येवमुक्तः स नराधिपेन ह्यवाक्छिरा दाशरथाय तस्मै । उवाच जातिं नृपपुङ्गवाय यत्कारणे चैव तपःप्रयत्नः ॥ 7-75-19 ॥
Thus addressed by the lord of men, that ascetic, with his head bent down, declared to that son of Dasharatha, the foremost of kings, his caste and the cause for which his striving in penance had been undertaken.
