It is well-known that the Beis Yosef ruled in his Shulchan Aruch that when a person mentions the Name of Hashem called the “Shem Havayoh” (Yud Kei Vav Kei) one should concentrate on the fact that He has always existed will always exist and is present now. When mentioning the Name of “Adnus” (Alef Daled Nun Yud) one should concentrate on the fact that He is The Master of everything. When mentioning the Name “Keil” or “Elokim” he should concentrate on the fact that He is powerful and omnipotent. It is well-known before Hashem that we are like drunkards because of all of our preoccupations and because of the evil inclination and because of our many sins and we are unable to concentrate our minds to think of these things every time that we mention the Name of Hashem. It is nevertheless incumbent on us to choose the minimum evil possible and therefore to try and concentrate on these things on the days that he can and the times that he can and on the Name of Hashem that he can. He should do everything that he possibly can and he will then receive reward for all of his work and one who comes to purify himself will receive heavenly help.
