Even the heavenly bodies have no hatred, jealousy, or competition. Never the less, they need peace. Peace is a very great blessing. There is no vessel other than peace that can hold a blessing. This teaches us that a blessing is nothing if it does not contain peace.
Peace is very great.
Rabbi Meir was once sitting and lecturing all Saturday night. A woman was listening to it and remained there until Rabbi Meir had finished. When she went home, she found that the lamp had already gone out. The husband was furious. He swore that he would not let her come into the house until she went and spat in the Rabbi's face.
