Dear Indology Members: Besides the Sanskrit textbooks already mentioned, Robert Goldman's and Sally S. Goldman's textbook, Devavaan.ipraves'ika is also quite effective. It comes with 4 cassettes as well. Ashok Aklujkar's method also comes with 5 cassettes. Madhav Deshpande's and Walter Maurer's texts are very useful as well. Lynken Ghose McGill University
