Musar su Salmi 37:7

And the commentators explain that three levels are mentioned here: 1) not being ashamed when his friend shames him, but possibly retorting. 2) compelling himself not to retort so as not to draw down upon himself through this even more shaming by his friend. 3) serving out of love and rejoicing in afflictions. That is, his not retorting stems from his loving the L-rd and accepting these afflictions with joy. And when he reaches the third level, he merits all this honor. For this trait comes to a man from the holiness of his soul and his pure faith in the L-rd that He directs all his ways, as it is written (Iyyov 34:21): "For His eyes are on the ways of a man, etc.", and He does all for his good. As we find in Midrash Tanchuma: "One should rejoice in afflictions more than in good. For even if a man receives good all of his days, his sins are not forgiven. And how is he forgiven? By afflictions. R. Elazar said: "A man must be grateful to the L-rd when afflictions come upon him. Why so? For afflictions draw a man to the Holy One Blessed be He, as it is written (Mishlei 3:12): 'Whom the L-rd loves, He chastises.'" If afflictions come upon a man let him suffer them and accept them. Why? For there is no limit to their reward. (Psalms 37:7): 'Be silent in the L-rd and hope [vehithcholel] in Him.' Hope in the L-rd. If He brings afflictions upon you, do not "kick" at them but accept them as chalilin (like "vechithcholel"), as flutes [of joy]." And toleration of shame is in the category of afflictions, as mentioned above, "who serve out of love and rejoice in afflictions."
