背道的兒女啊，歸回吧！我必醫治你們背道的病。«看哪，我們來到你這裡，因為你是永恆者我們的上帝。»
Takanat HaShavin
Collection regarding matters regarding repentance to those who repent from Jacob. In the Gemara Yoma [86a], "Great is repentance etc." see ibid. there are 7 saying regarding the greatness and advantages of repentance. And it is known that repentance follows understanding of the heart as is written "and their hearts will understand and they will repent" and because of this it said that repentance is after understanding as they [the Talmudic Sages] said in Megillah [17b]. It it also known that there are 7 levels in the instantiation of an action from understanding of the heart until completion of the action which correspond to the essential 7 sefirot [revealed in this lower world] Chesed, Gevurah, Tiferet,Netzach, Hod, Yesod and Malchut and corresponding to them is all the lists of 7 and so too the 7 greatnesses of repentance: "[Great is repentance] that it brings healing to the world (Yoma 86a)" and it appears to me that the healing of forgiveness in accordance with the language of the verse "I will heal their backsliding" (Hosea 14:5)
