Lump of sugar

When Rabbi Shlomo of Karlin drank tea or coffee, he would take a lump of sugar and hold it in his hand while he drank.

His son once asked:

– Dad, why are you doing this? If you need sugar, put it in your mouth, and if you don’t need it, why hold it in your hand?

-When he finished drinking, Rabbi Shlomo gave this lump of sugar to his son and said:

– Try it!

The son took it, put it in his mouth and was surprised, not tasting any sweetness.

Subsequently, when his son talked about this, he said:

– One who has cognized the unity of everything can taste the taste with his hand as with a tongue.
