Science now has a simple test to see if vegetative-state people are aware of the world. This raises many ethical questions.
Doctors can do NOTHING for them.... so:
1. ask them if they want to be euthanized?
2. let them vegetate?
3. require frequent MRI's to "talk" to them? (costly - unfortunately)
where does Theosophy stand?
It might relieve some of their anxiety if we offer taped prayers. Possibly teach them to meditate if they are interested.
It is probably a horrible existence... Panic/Anxiety for one.
