Chasidut su Salmi 69:78

Master of the Universe, who causes life, Living God and Sovereign of the world: Have mercy on us, give us life and sustain us. Sanctify us and purify us from the impurity of death which is the greatest source of impurity, which is (the Granddaddy) the highest category of impurity. They are the stirrings of adultery that overpower and spread out in the world greatly, until "we are sinking into the slimy deep, and find no foothold, we have come into the watery depths and the flood sweeps us away." (paraphrase Psalm 69:3). We merited in the strength of the holiness of the Mitzvah of Purim that we should merit to receive and to continue upon us the holiness and purity of the completely Red Heifer, to purify us in truth from the impurity of death in this world and the next world. And may I merit in this way to receive the Festival of the Holy Pesach, the time of our Freedom in great holiness and great and all-encompassing joy. And may we merit in Your mercy to fulfill all the mitzvot of Pesach in great holiness, happiness, and great joy. And help us, save us, and guard us in Your great compassion, from any amount of chametz or leaven, should not be found in our boundaries or property, absolutely any amount of leaven or chametz all the days of Pesach. For it is revealed and known before You, Master of all the world, that it is impossible for flesh and blood alone to be careful about a miniscule amount of chametz without Your saving grace. Be compassionate upon us with Your great compassion, redeeming strength, true mercy, guard and save us from any amount of chametz all the holy days of Pesach, and help us and cause us to merit to go from slavery to freedom, from sadness to joy, from mourning to festival, from darkness to great light. Cause us to merit to organize the Seder of Pesach with great presence, wonderous passion, and all encompassing happiness. May we merit that should come upon us and cause enlighten within us, in this wonderous enlightenment all of the expansive and small mind that cause the light of Pesach in the great, wonderous, and awesome light.

Once, I had been complaining to him about my problems and I said to him bitterly, "I am worn out from my crying, my throat is hoarse, my eyes are spent from hoping for my G-d" (Ps. 69:4). And he raised his hand and said gently, "If so, what is there to do?" (In other words, it is forbidden to question the ways of G-d, and G-d is surely righteous). Afterwards he answered and said to me, "If Kind David a"h said "I am worn out from my crying, my throat is hoarse", surely he meant it literally: he had already cried out so much that he was physically exhausted and his throat was literally hoarse. But you, thank G-d, still have your strength.
