When you have the indwelling Holy Spirit Of God, he resides in your heart, not in your head. However, everyone in the kingdom of God either routinely or occasionally speaks from their head when they speak through the realm of the spirit, yet expect to be speaking solely the words that God would have them speak, and in the manner that he would have them speak.
If you speak from your head, you have not connected with God, are not speaking his words, and are not likely to achieve the same results that he would have achieved under the same circumstances. Pray in the spirit, from the heart, that whenever you speak in the realm of the spirit, you will speak only from the heart. Practice doing so now by focusing on your heart, and vocalizing only the sounds that rise from your heart.
Most importantly, when you seek guidance from the indwelling Holy Spirit Of God, speak to him in your heart where he dwells, and listen in your heart for his response. Be careful to vocalize until there are no further sounds coming up from your heart, and to listen until you are confident that there is nothing further that is being said.
