Chapter 5, part 1, siman Gimel:
On the measure of help from heaven in a miraculous way in the steps of Moshiach: The help from heaven in general and in a miraculous way in particular comes measure for measure. In the measure that a person measures out, it is measured out for him in heaven, that is to say in the said measure that the act of a mitzvah is done by a person in action in a natural way, in this measure comes the help from heaven, level against level, on the principle of 499.5 from the left and 499.5 from the right according to our rabbi the GR"A in many places (and in particularly in his works Yahel Ohr Sod Barak haShachar). And if one would ask how is it possible to act going in to something, and more so to actively endanger oneself while depending on half natural and half miraculous, for we do not rely on a miracle going in to something. But the calculation is that the miraculous side goes up by many percentage points and on many sides, and in what is related to actions of the Footsteps of Moshiach, and more so on actions done by the community, the calculation is, per the explanation of the GR"A, that the miraculous help from heaven is greater than simply measure for measure, and sometimes the help from heaven goes up to a thousand times more. And the calculation is like this: The highest level of the Awakening from Below, in what is possible and also in what is required of the individual and the community, to arrive and to achieve in action, both per repairs, and also actions of salvation, is the level of 999 in Yesod (Likutei haGR"A), which is the "thousand rivers" (Zohar VaEra 2:27b), as is known, which is held up in the calculation and in the power of the 2 hosts, like the explanation of our rabbi the GR"A in many places, which are in Netzach and Hod, which are the "legs", "the legs standing as cypress", which are the 2 Moshiachs. The last level of Alef is completed by the small Alef of Zeir Anpin, in the secret of "the smallest one shall be for a thousand", which completes the number of 500 from here and 500 from there, which are in Netzach and Hod, which is in Vav and in Heh. According to this, behold in every level which is done by the left line, which is the attribute of din in a natural way, the right line immediately joins it, which is the attribute on chesed, in a miraculous way. And when the activity is done by the community, the individual merits of each person are added on, according to the root of the soul, from the middle line, the line of rachamim, on the entire nation. And all the more so when it is the work of Kibbutz Galuyot, about which it is said "with great Rachamim I will gather you". And when the last level of Awakening from Below is reached, which is 999 levels, which is the completion of 999 in Yesod, in the 3 worlds, and their completion by the small Alef, immediately is added upon them the Upper Shefa of the Great Alef of Arich Anpin, wherein every Alef is 1000 times from the lower Small Alef of Zeir Anpin, for it dwells in the Yud and Heh (as two friends that do not separate), and it is all in the Upper Shefa and in a miraculous way. As is known, the blessing of Hashem comes from the Shefa of the Great G-d, and that is the meaning of the verse: "He will add upon you like yourselves 1000 times and bless you" etc. Also from here is the calculation of "one shall pursue a thousand".
