The upper light that comes to a person in response to his efforts, which connects him and makes him suitable for spiritual action, is called a blessing. Therefore before each action, we need to come to a blessing.
Blessing means that I have reached restriction, screen, and reflected light, and therefore I can already receive direct light and work with it to the measure of my blessing. The force of bestowal I acquired within my will to receive is called a blessing.
Therefore before each action it is first of all necessary to reach a blessing: to bless the Creator for giving me the opportunity to perform an action with the intention to bestow.
