After enduring a series of shocking visions in Jerusalem, the prophet is returned to the exiles in Babylon [ביאור שטיינזלץ]. The primary approach among commentators is that this journey to Jerusalem and the subsequent return did not occur in physical reality. Rather, it was a deeply spiritual experience taking place entirely within a prophetic vision. Since the prophet was already physically living in Babylon, this return is a shift in consciousness, bringing his mind back to his natural surroundings through the spirit of prophecy [רש"י, מצודת דוד, רד"ק].
The prophetic spirit serves as the active force that carries him, transporting his awareness back to the land of Chaldea, which is Babylon [מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. Once he is mentally back in his physical location, the prophetic vision fully departs from him [מצודת דוד, ביאור שטיינזלץ]. This lifting of the vision is not merely the conclusion of a spiritual encounter. Instead, it represents the specific moment he is granted permission to open his mouth and speak to the people, sharing everything he has just witnessed [רד"ק].
