I disagree. While the Spirit does work through the psyche, the Source of the gift is not in onself, but it is from God.
I think this description applies better to those that are faking it, or whatever “noise” they are doing.
Although it is possible to pray in the spirit without engaging the mind, the Source is not “emotion”. While one may feel emotion, one does not necessarily. The Spirit exists separately from both intellect and emotion.
I agree that adoration is a central focus, however, it is not the only one. These other types of prayer do not necessarily require intellect either.
If you have ever prayed for others, and did not know what their needs were, but desired that God meet their needs, then such a prayer can be made in this fashion. God knows the desires of the heart, even without the formulation in the intellect of words.
And a case can be made for getting both the emotions and the intellect out of the way, so that the Spirit can pray through one without impediment.
