Synopsis Mandana Misra Spotisiddhi theory tells us how the meaning of a sentence is communicated. But his theory was attacked by the opponents and then Mandana Misra has answered the issues raised by the grammarians, and philosophers. Although the Sphota doctrine of Mandana Misra is not appreciated by Modern linguists, yet many later Grammarians have dealt with the Sphota problem following the philosophy of Mandana Misra. This book deals all these issues in a systematic way.
