Let me break down the main post, just because it's amusing to me.
1. If it requires that much 'focus', as you like to call it (thus why the ' '), then your not ready, by any stretch.
2. Manifestation into the physical plane? NOT going to happen. In fact, I wonder what cartoons your watching to even think this possible. Bleach? DBZ? What?
3. This part, which amused me the most, is that you said that it disappears back into the 'spiritual AND etheric realms'. It's ONE OR THE OTHER, NOT BOTH. For something to do BOTH would be a belligerence to both and would most likely cause attacks from BOTH that may exist.
4. Apparently you have no knowledge of EITHER the spiritual or ethereal realms, or else you would NEVER call them by what you just did.
5. Pyro, electro, cryo? Really? You can't even 'master' a simplistic aspect of ONE, but yet you post such? It honestly makes me wonder why people even bother responding.
