In recent days, Rabbi Kook has asked several times to drink a "cup of black coffee" - Turkish coffee.
According to his associates, he does not drink black coffee at all, and that this is "a rare thing for him.".
One of his associates said: I heard about the Kabbalist gaon Rabbi Chaim Sinwani, zt"l, that when he drank a cup of black coffee, he would also place a cup of water in front of him, and he said that this was a form of sweetening the laws, because "black" coffee is a form of "powers" and water is "charity.".
Because of this, he asked to bring a cup of water to his master, in order to work to sweeten the judgments upon the people of Israel.
But the Grand Master Cook responded: "I am not in a position to direct these things... I do not belong in this... I drink coffee because I need to wake up... I have weaknesses, I fall asleep like this...""
Regarding the intention of the Kabbalist Rabbi Chaim Sinwani, he said: "Doesn't 'kos' arise in the gematria 'Elohim', which indicates the quality of the law as known, and the name 'El' in its full form arises as the number Kafa, and it is the name of grace, as it is written 'Chesed El koll hayom', and we find 'kos kafa' - the sweetening of the laws.".
And he added: "Hence the root of the yishna da'ma, when reconciling and sweetening the law, to say to each other, 'Come, let's sit down for a cup of coffee'... and especially when adding sugar to a cup of coffee, which indicates sweetening.".
The associate said that he once heard from Rabbi Kook that it was customary to pour milk on coffee, as a form of light in the darkness, because black coffee is a form of darkness, and white milk is a form of light - and this also indicates the abundance of kindness and the sweetness of judgment, because milk is the acronym for "to say your kindness in the morning.".
