Blessing G-d

 Berachos (07a) I once entered into the innermost part [of the Sanctuary] to offer incense and saw Akathriel Jah, the Lord of Hosts, seated upon a high and exalted throne. He said to me: Ishmael, My son, bless Me! l replied: May it be Thy will that Thy mercy may suppress Thy anger and Thy mercy may prevail over Thy other attributes, so that Thou mayest deal with Thy children according to the attribute of mercy and mayest, on their behalf, stop short of the limit of strict justice! And He nodded to me with His head. Here we learn incidentally that the blessing of an ordinary man must not be considered lightly in your eyes.
