Experiencing a prophetic revelation is an overwhelming event that completely drains a person's natural reserves. To survive the sheer intensity of the encounter, Daniel requires outside assistance. The angel touches him an additional time, an action specifically intended to provide a second surge of strength [מלבי״ם]. During this moment, the angelic figure maintains the human form he had adopted earlier [מצודת דוד, ביאור שטיינזלץ]. On a deeper level, this human appearance indicates that the prophecy itself is being filtered. It is presented in a thicker, more tangible form, condensed down to human proportions so that Daniel can safely endure the experience and remain stable [יוסף אבן יחיא].
The process of gaining strength is not merely symbolic. Daniel actually feels a real, physical transfer of power entering him [ביאור שטיינזלץ]. This renewal of energy operates on two parallel tracks simultaneously, restoring his physical body while also reviving his mental and emotional capacities [מלבי״ם]. Furthermore, this vital energy is not transferred solely through physical contact. The angel also fortifies him through the words of comfort and encouragement that are spoken immediately afterward [מצודת דוד].
