“Noah was a righteous man.” Even Ezra interprets “righteous” in good deeds, “whole” in his heart, “in his generations,” some condemn and some praise. In generations of wicked ones, when the thoughts of the generation are that it is not worthwhile to work in order to bestow, the body sometimes praises, meaning that his view is with his contemporaries. And sometimes, it condemns what his contemporaries say.
At that time, he has the choice to do good deeds, meaning that he can overcome through actions. However, man has no control over his heart, to be able to change the feeling in the heart, if the heart feels what his contemporaries tell it, and the heart takes after the majority.
For this reason, there is no other choice but to overcome through actions, perform acts of bestowal, and ask the Creator to give him another heart, as it is written, “Purify our hearts.” However, in the argument, he cannot succeed. When he becomes righteous in terms of the practice, he is rewarded and becomes whole in his heart, as Even Ezra said.
Afterward, he comes to a state of “Noah walked with God,” meaning that when the Creator is revealed to a person, when he begins to feel the existence of the Creator, he has no choice but to annul as a candle before a torch. At that time, he is unimpressed by what he hears from his contemporaries because they all annul before the light of the Creator.
According to the above, it follows that “whole” comes after he overcomes in practice. At that time, his wholeness comes to complement all the flaws he had before. This is as Baal HaSulam said, “Tamim [whole] has the letters of Tav-Mayim [Tav-water], which is only on one who knows how to deceive himself and sees the truth as his eyes see it, yet still accepts everything in wholeness.” This is called “faith above reason.”
