As the final letter of the Hebrew alphabet, TAV is equal to the number four hundred and is symbolic of perfection.
The word TAV means ‘impression’ or ‘mark’.
TAV alludes to the three essential services of the soul: teshuvah (repentance), tefillah (prayer) and Torah (all three of these words in Hebrew begin with the letter TAV).
TAV represents truth.
The letter TAV begins the word tikkun (redemption). This refers to the concept of teshuvah (a returning to the Source for forgiveness).
