Halakhah for Arakhin 32:2

It is from the root of the commandment that he take his distancing from people as an example for his soul. As a person is distanced from all good as a result of sin, in order that he will repent from his evil way. And this is [the meaning] of their, may their memory be blessed saying (Arakhin 16b), "With evil speech, he separated a man from his wife and a man from his fellow. And therefore his tent is outside of the camp." And therefore it is fitting that he should call to every man that they veer away from him. And the general principle in all things is "With the measure that a man measures, [so] will he be measured" (Sotah 8b). And many do not know the understanding of this thing. As they think to explain this thing with God, may He be blessed, modeled on the recompense of men - that each one will recompense his fellow according to the good that he did by him, or according to the bad [that he did]. But the matter is not like this with God, blessed be He, - God forbid. As there is always only kindness and mercy with God, blessed be He; and His goodness is ready at every instant and every hour for all who are fitting to receive it. And 'the Guardian of Israel does not slumber and does not sleep.' [Rather] the intention of that which they, may their memory be blessed said about Him, blessed be He, "With the measure that a man measures, [so] will he be measured," is to say that according to the action of a man - whether for the good or the opposite - will he be set to receive recompense. As always in the same manner that a person sets his thoughts and does his actions - in that exact mold - will blessing or its opposite be drawn to him.
