Musar su Amos 3:7

For this reason let him arouse himself to the best of his ability to pray with tears before the Holy One Blessed is He. This is elaborated upon in the Zohar, Parashas Vayikra (15a): One day Rabbi Shimon ben Yochai was sitting in the gate of Lod. He lifted his eyes and saw the sun shining. Then its light became blocked, after which it again shone and again was blocked and again shone and again was blocked. This recurred three times. Meanwhile the light dimmed and the sun became black and green. Rabbi Shimon ben Yochai said to his son Rabbi Elazar, “Follow me and let us see what this means. Surely an evil decree has been issued and the Holy One Blessed is He desires to inform us of it. For whenever a decree is issued On High it is suspended for three days until the Holy One Blessed is He has informed the righteous, as it is stated, “For Hashem, God does not do anything without revealing His secret to His servants the prophets” (Amos 3:7).
