However, the communication starts at the thought level. From the highest realms of our thoughts. In the superconscious levels of the mind, the communication is passed down to our souls (this is the domain of the mid-mind, morontia mind) and then to our conscious mind, our brains, our senses, our feelings - the electro-chemical parts of our being. As the communication travels or goes from the superconscious mind down to the conscious mind, it might get diluted or corrupted because of our animal or carnal nature, our ignorance, etc. It might be interfered with. This is a major reason why one has to be careful NOT to rush to conclusions to say, "Thus saith the Lord." 

 

If you are actually growing intellectually and spiritually, you should find it easier to ascertain or properly identify the divine messages. The closer you are to God, the more mature you become, and the easier it becomes for you to receive your TA's messages, understand them, interpret them properly, and execute them effectively. And yes, sometimes, you can literally, audibly hear your TA (indwelling spirit Thought Adjuster; God the Father in you) speak to you with a human voice, in your own language. It's always very, very beautiful, filled with love! Hallelujah! Namaste! Glory!
