TRO11, could you please shed light on the following:
I once read the following story. About a hundred and fifty years ago, a discovery was made about a certain vein in the brain that assists with memory.
When told to this great Chassidic Rebbi, he said that it’s already mentioned in the Zohar, as follows:
That there is a certain vein in the brain that when it’s in an upwards position it assist in remembering. That is why when people try to remember something they instinctively lift their head upwards. On the other hand when trying to concentrate one, instinctively bends his head down.
Does this vein ring a bell?
