That's pretty much it. It's a raw surge of chakra from your body, A rank in strength (Thus a good counter for genjutsu), of fire.
If hit by a wind jutsu, you can absorb it and then release it back, as a combo. Of course, it requires the wind to be of the same or lower rank, otherwise it will just neutralize the fire (S rank). If the fire is neutralized, then it simply vanishes, along with the wind jutsu, without burning you.
