“Introduction of The Book of Zohar,” Article “The Two Points,” Item 121: Over all the locks, we receive a special degree in His Providence, and they become openings, degrees of attainment of the Creator. And those degrees that we receive on the openings become halls of wisdom.
Thus, the locks, the doors, and the halls are three forms that come upon our substance, the desire to receive in us. Before we turn it into reception in order to bestow upon our Maker, that substance turns the light to darkness and the sweet to bitter, according to our taste, since all the conducts of His Providence remove us from Him.
At that time, locks are made from the desire to receive in us, and after we repent, we are rewarded with receiving in order to bestow, all the locks become doors, and then the doors become halls.
All of our obstacles become transformed into desires filled with the Light, attainment, understanding, and awareness of the force of bestowal.
