Hikari

As long as I know, Hikari is a japanese word for 'light' or 'ray'.

I wonder if there's any difference in japanese between the light reflected by something and the light emitted by something that radiates. It's easy to reflect what others share, to be a hub; it's amazing to see how consuming can sharing be. Radiating, generating things on our own to share with others. Seems like it's worth the effort, tho.
