In the previous study of Teruma DZ 2049 (http://dailyzohar.com/daily-zohar-2049/) paragraph #46 the Zohar reveals that those that connect and share the Light with the wicked are called in front of the King and Queen because they reveal light in dark places. Two witnesses that are of the eyes of God that watch the people’s action, come to testify about the good deeds of those people.
“בְּכָל-מָקוֹם, עֵינֵי יְהוָה; צֹפוֹת, רָעִים וְטוֹבִים”
“The eyes of YHVH are in every place, keeping watch upon the evil and the good”
There are great merits earned when helping people elevating spiritually, especially from darkness to Light.
The first time a person transforms himself by leaving the ‘bad’ ways of the past and into the ways of the Torah, he connects to Keter and draws great light. The person that helps another with this connection of transformation becomes a channel for the Light of Keter that the other person connects to. This light flows from Keter to Chokmah (father) and Binah (Mother) and Da’at. The father of that person, alive or not, also benefit from the light that is revealed.
Every revelation of light that we do in this world affects our spiritual line. The sages say that to be protected from the hardship of the days before Mashiach, we should do good deeds and study Torah. The Zohar is the highest level of Torah study. Avoid the bad and do good, not just because the eyes of God see everything but because it is good for you and your future.
