The Vedas are said to be the oldest literature of India, or perhaps of the world. Ages passed, and gradually it became difficult for ancient Sanskrit scholars to under-stand the Vedas. From time to time, traditional Vedic scholars tried to interprete the Vedas. Their names are found in the quotations but their works are not available. In 1400 A.D. Sayarjacarya, a great Vedic scholar wrote an exhaustive commentary on the Vedas. In his introductions to his commentary of the Vedic Samhitas, he has given some principles, some guideline, for the interpretation of the Vedas. These introductions have been studied and taught by Sanskrit Pandits in a traditional manner, but it is not so in case of the modern scholars. They have gone through Sayana's commentary, but his introductions have not been touched by them owing to difficult language and difficult Sastrartha.
The author of this book has made an attempt to critically analyse and translate Sayana's introductions to the TS and RV. The introductions have been translated into English for the first time. We hope they will be helpful for the modern Indian as well as the foreign scholars to understand Sayana's principles of Vedic interpretation.
