“ For Rosh Hashanah is the first of the Ten Days of Repentance, and the essential repair of repentance is by the aspect of the ten types of melody, which are the entirety of joy, the aspect of reversing grief and sorrow to joy as mentioned. And as discerned in Rabbeinu z"l's words in many places, how much a man who is far from serving Hashem needs to rise up and make himself happy by any possible means of still finding in himself any good point. ”

“ For, every man, as long as he has pity on himself, and considers the eternal purpose, needs to very, very much enliven himself and to see, to seek, and to find in himself some good points, what he has ever done, some mitzwah or good things, in order to not be entirely downcast, and to accustom himself to make some joyful melody from time to time, especially on Shabbatoth and Yamim Tovim, when we need to be very, very happy in all sorts of joys from evening until morning, and make a great deal of joyous melody. ”

“ Laws of Procreation and Laws of Matrimony Halakhah 1 "A Kohen is forbidden to marry a divorcee, promiscuous woman, or challalah... Kohanim, Levi'im, and Yisraelim are permitted to one another, and the child is [a Kohen, Levi or Israel] according to the male parent. Levi'im, Israelim, challalim, converts etc. are permitted to one another.”
Oth 1 See the [Likutei Moharan Ch. 61] torah on Chadi Rabbi Shim`on from beginning to end; take a good look at it. And the rule is: everything is interconnected, and it is all one [thing] , for they all belong to one aspect. ”
