Chandra is born to one of the Sapta Rishi Athri and Anushuya. He married 27 daughters of Prajapathi Datcha. But Chandra was not equally in love with all of them and loved one of them Rohini more than others. When this issue is escalated to the father of them Prajapathi Datcha, he cursed Chandra to lose his 14 arts gradually day by day. Then Chandra lost all his arts as the result of Datcha's curse.

When Chandra lost all his arts, he did severe penance towards almighty Lord Shiva. After a long time, Lord Shiva gave him a resolution that as per Datcha's curse Chandra will lose his arts one by one daily and after 14 days, Chandra will gain those arts one by one daily.

By the way, deminish of 14 arts become Krishna Paksha and the growing of 14 arts of become Sukla Paksha. As Chandra love Rohini more than any other wives, he is in exalted mode in the star Rohini, rashi Rishaba.

If Chandra (Moon) is powerful and malefic in a horoscope, then it could make the native as adamant.
