Dashadhyayi (DevanÃÂgarë: , IAST: ) is a commentary on the first ten chapters of VarÃÂha Mihira's Bá¹Âhat JÃÂtaka, written in present-day Kerala, India. This text was regularly studied and memorised along with Bá¹Âhat JÃÂtaka and its interpretation of terms readily accepted.
Earlier scholars considered the 13th-century author Govinda Bhattathiri alias Govindan to be the author of Daà ÂÃÂdhyÃÂyë, and its earlier version Nauka. According to B. V. Raman, Govinda has very intelligently tried to read some secret or hidden meanings into VarÃÂha Mihira's writings other than they would ordinarily imply. However, M. Ramkrishna Bhatt theorized that either the author of Daà ÂÃÂdhyÃÂyë was Govinda and the author of Nauka some other writer who is not yet known, or Govinda Bhattathiri did not write Daà ÂÃÂdhyÃÂyë.
Recent research suggests that Govinda only wrote Nauka, another commentary of the entire Brihat Jataka text with same style and language during the 13th century. Daà ÂÃÂdhyÃÂyë appeared during 15th century with same narrative style but for only ten chapters of Brihat Jataka. It is now evident that Daà ÂÃÂdhyÃÂyë is an abridged version of Nauka, rearranged by some teacher of later school. The authorship of the Daà ÂÃÂdhyÃÂyë was assigned to Govinda Bhattathiri in the Ithihyamala written by Sankunni during late 19th century.
was primarily written in simple language and style for the benefit of the author's disciples. It is based on experimentation and observation; he has focussed on prediction and profusely quoted sources. He has followed more the views of SÃÂrÃÂvalë on which basis he has also criticized VarÃÂha Mihira. With regard to the value and importance of Daà ÂÃÂdhyÃÂyë, which commentary is the foremost amongst the twenty-eight commentaries on , Harihara, the author of Praà Âna MÃÂrga, states that: <blockquote> Sanskrit: à ¤ à ¤¦à ¥Âà ¤·à ¥Âà ¤Âà ¥Âà ¤µà ¤¾ à ¤¯à ¥ à ¤¦à ¤¶à ¤¾à ¤§à ¥Âà ¤¯à ¤¾à ¤¯à ¥Âà ¤ à ¤«à ¤²à ¤®à ¤¾à ¤¦à ¥Âà ¤·à ¥Âà ¤Âà ¥Âà ¤®à ¤¿à ¤Âà ¥Âà ¤Âà ¤¤à ¤¿ à ¥¤ à ¤Âà ¤Âà ¥Âà ¤Âà ¤¤à ¥Âà ¤¯à ¥Âà ¤µ à ¤¸à ¤®à ¥Âà ¤¦à ¥Âà ¤°à ¤¸à ¥Âà ¤¯ à ¤¤à ¤°à ¤£à ¤ à ¤¸ à ¤ªà ¥Âà ¤²à ¤µà ¤ à ¤µà ¤¿à ¤¨à ¤¾ à ¥¥à ¥©à ¥¨à ¥¥ <br /> IAST: adá¹Âá¹£á¹Âvàyo daà ÂÃÂdhyÃÂyëṠphalamÃÂdeá¹£á¹Âumicchati à ¥¤ icchatyeva samudrasya taraá¹Âaá¹ sa plavaá¹ vinÃ à ¥¥32à ¥¥<br /> <br />English Translation by B.
