Vishvamitra said It is not seen that a person commits a grave sin by taking interdicted food. It is only an oral precept which says that one becomes fallen by drinking wine. The other forbidden acts,-in fact, every sin,-cannot destroy one's merit.
विश्वामित्र उवाच नैवातिपापं भक्ष्यमाणस्य दृष्टं सुरां तु पीत्वा पततीति शब्दः। अन्योन्यकार्याणि यथा तथैव न पापमात्रेण कृतं हिनस्ति॥
