Afterwards: Here we are referring to two stages. A first stage when the learning is as new but not quite new. The next stage is when the Torah study is in a manner of Chadoshim Mamosh! Actually new. And not just like new.
Knowledge: Recognition and a Feeling for G-dliness
The ultimate unity of Nissuin: Full marriage. And full connection through knowledge and attachment to Hashem.
Concept of Knowledge
As the Alter Rebbe writes in Tanya: Daas, whose etymology may be found in the verse: וְהָאָדָם, יָדַע אֶת-חַוָּה “And Adam knew Eve”, (‘Knew’ as in the Biblical sense) implies attachment and union. (As applied to Daas of the divine soul, this means) binding one’s mind with a very firm, strong bond and ‘firmly fixing one’s thought’ on the greatness of the blessed Ein Sof, without diverting his mind from it (i.e., the subject matter conceived in Chochmah and developed in Binah is absorbed in the mind by concentration, Daas.)
For even one who is wise (by utilising his faculty of Chochmah) and understanding (by exercising his faculty of Binah) in the greatness of the blessed Ein Sof, yet, unless he applies his Daas and fixes his thought firmly and diligently on his understanding of G-d’s greatness, he will not produce in his soul true fear and love, but only vain fancies. He will only imagine that he fears Hashem and loves Him. True fear and love are attained only by way of Daas. Thus, Daas provides the substance and vitality of the Middos (and is therefore termed a “mother” of the Middos, another parent side by side with Chochmah and Binah). It comprises Chesed and Gevurah; That is to say, love with those other Middos that are its offshoots, and fear with its offshoots.
Firmly Fixing One’s Mind
This is about focus and ignoring disturbances.
Include All the Mitzvos
The Alter Rebbe in Tanya (Perek 4) says: For love is the root of a Jew’s observance of all the 248 positive commands; from it they issue forth, and without it they have no true substance. For he who fulfils them in truth, is he who loves Hashem’s Name and who truly desires to cleave to Him. Now, one cannot truly cleave to Him except through the fulfilment of the 248 positive commandments, for they are the 248 “organs of the King” (of Hashem, King of the universe), as it were, as is explained elsewhere.
Fear is the root of one’s observance of the 365 prohibitive commands, for he (the G-d-fearing person) will fear to rebel against the Supreme King of Kings, the Holy One, blessed be He. Or a deeper level of fear — that he feels ashamed before Hashem’s greatness, so that he will not rebel against the all-seeing eyes of His glory by doing what is evil in His eyes, namely, any of the abominable things hated by G-d, which are the Kelipos and Sitra Achra (the “other side” — that which is the opposite of holiness), which draw their nurture from man below (in this world) and have their hold in him so that they be able to derive their nurture and life through him through his violation of the 365 prohibitive commandments.
