Shri Ekanatha Charitam II Vol III Book VIII Chp 12 Shlokas 22 - 26
यवन उवाच
गण्डूषे तु मया विप्र कृतेप्येवं पुनः पुनः |
न क्रोधवशमापन्नः स्नात्वा गच्छसि सुस्मितः ||
क्षमां विलोक्य ते स्वामिन्नाक्ष्चर्यं परमङ्गतः |
पृच्छामि त्वामादरेण तत्र कारणमुच्यताम् ||
एकनाथ उवाच
गण्डूषोच्छिष्टदोषो मे नूनं स्नानेन नश्यति |
किन्तु मे क्रोधदोषस्य शुद्धिहेतुर्न विद्यते ||
तस्मादेव क्षमां त्यक्तुं नाहमिच्छामि सुव्रतः |
क्षमयैव मनःशुद्धिर्जायते यवनोत्तम ||
मनःशुद्धिविहीनानां देहशुद्ध्या तु किं फलम् |
पूजां गृहाणि भगवान्नूनं हि प्रयतात्मनाम् ||
The muslim said
Oh! Brahmana! Even after my repeated spitting on your head you did not get angry. With a smile, you were taking bath again and again and going home. Oh! Sir! I am very much surprised to find you so patient. I ask you this question with all sincerity. What is the reason for this limitless patience and forbearance.
Ekanatha replied
The impurity caused by your spitting can be removed by a bath. But there is no way to remove the sin born out of anger. Oh, good one! I do not like to give up endurance. The heart is cleansed only with endurance. What is the use of a clean body alone if the heart is not pure? Shri Bhagavan approves of the Pooja performed by only those who have both a clean body and a pure heart.
