I can’t really answer that one other than to lean on my personal experience, which is that sitting and quieting my mind is what works for helping me maintain balance, and I get a different but equally joyous feeling from listening to the most violently aggressive and chaotic music I can find. What I can tell you is that you may be accessing a sort of concentration meditation. There are many techniques, some involve trying to empty the mind and let thoughts flow through like leaves floating on a river, some involve checking in with all the individual parts of your body one at a time, concentration meditation involves hyperfocusing on one thing to the exclusion of all others. I think that might be the space you’re in. If you’re curious to find more, Buddhist Geeks has a wiki with a great set of tutorials on focus meditation.
