In letter Same’kh- Te’t(69) Baal haSulam says that after we have been introduced to the notion of Tzimtzum Bet in general, which takes place in Partzuf haNekkudot deSa”G and which is done for the needs of the creation of Esser(10) Seffirot(E”S) deOlam haNekudim, which is the 4th Partzuf of the world deA”K, we are going to follow the creation of Ten Seffirot of the world of Nekkudim in more details.
The creation of Partzuf out of Partzuf has already been discussed, where each lower Partzuf is born and comes out of(=on the basis of) Massakh deGuf(body) of the Prior=Upper to It Partzuf after Hizdakhekhut(lessening) and Illi’ya(ascend) of the Massakh deGuf of the Upper Partzuf to be Peh(mouth=Malkhut deRosh) for the purpose of Zivug(interaction) of possibility of unfold of another level of potential of the creation. The reason for the lessening( Hizdakhehut) of the Massakh is Bitush( fighting) between Ohr Makif(surrounding Light) and Massakh( the Power of Will) of the Upper Spiritual structure( Partzuf). This Bitush makes Hizdakhekhut (lessening) of the Power of Will( Massakh) from its Ovi’ut( intensity) which is found on the level of Guf( body=activated power of will) of this Partzuf and makes Massakh to be equal to the Ovi’ut(intensity) on the level of Rosh( head=potential power of will, as is explained in letter 35).This explanation of the way of creating a new Partzufim is also true for the Partzuf deA”B deA”K(Hokhma)which comes into being from Partzuf Ketter(Galgaltah), and in the same way Partzuf Sa”G(Binna) deA”K originates from A”B deA”K and so here, says Baal haSulam, the 4th Partzuf deA”K (which is called M”A) and which is also called Ten Seffirot of the world of Nekkudim originates and comes into being from its Upper Partzuf which is Sa”G deA”K in the very same way It is created.
