With experience. Gods doesn’t say bs and emotional crap. Nothing of what would make you think and going nowhere or do nonsense, what would not advance you. Nothing of lowering of your energies. Short and straight to the point, uplifting, getting you going, not what you expect or want to hear. More pure Soul clearer it can transmit this.
By reading the website of the Temple of Zeus, and therefore knowing what to expect and what is possible.
Also, all I can say is that when a God puts some of His attention on you, or wants you to know something, YOU WILL KNOW. Period.
