Isn't this just the introvert extrovert personalities we have? I tend to be introvert and hang in the hallway but it is good to be put into those other situations to grow.
One thing I can say is being an introvert in an extrovert environment can sure be exhausting. Its like all the goings on around me just start to drain my energy as I try to keep up with it.
Another great post @jiva34
The common definition of personality is only useful in describing the mind, its operation, and its interface to the material manifestation, and that definition is deceptive. Mind is another covering of jiva, mind has a locus (the brain, although that gets a little fuzzy these days) within the covering shell of the material body, all covered by karmic conditioning. The jiva is outside/underlying all of those ephemeral coverings, but it is NOT ephemeral.
