From The Maagid – MEMORY / TESHUVA When we sin this causes us to be forgetful (like any addiction – we lose our mind) when we do Teshuvah (return to our soul) we remember – this is simalear to the olive, for the olive itself causes forgetfulness, while the olive oil causes memory – now hidden within the olive is the oil – similarly hidden within the sin is the (eventual) repentance.
