SHOULD WE NOT USE INTELLECT?
Not a bit, you may use your intellect, but not at the cost disobeying My orders. You may think as long as you have a mind you have to think. Your mind never stops thinking. It will tell you that it could not be night when your eyes see sunlight.
Remember not to let your mind lead you to disbelieve in the Masters word. You must think and understand that there is some important reason and purpose behind whatever benefit of others. Whatever He does, is always for the best. So do as the Guru tells you and let the mind think as it likes. That is enough.
