Who was the writer of sant dnyaneshwar at the time of dnyaneshwari?

Type your answer here... sat chit ananda baba was the writer when sant dynaneshwar preached the dynaneshwari! He was the man, who was proclaimed dead, but when saint dynaneshwar saw his dead body and his wife lamenting near to it, he gave him new life by sanjivani vidya as Sant Dynaneshwar was full fledge understanding of YOGA.
