Hayyim ben Joseph Vital (Hebrew: חַיִּים בֶּן יוֹסֵף וִיטָאל; Safed, October 23, 1542 (Julian calendar) / October 11, 1542 (Gregorian Calendar) – Damascus, 23 April 1620) was a rabbi in Safed and the foremost disciple of Isaac Luria. He recorded much of his master's teachings. After Vital's death, his writings began to spread and led to a "powerful impact on various circles throughout the Jewish world." Source: Wikipedia (en)
