The "Dharmic religions" don't agree on "eternal self", but they do generally agree that the immediate impression that feeling in the hand is consciousness _in the hand_ rather than a brittle illusion produced in a particular part of the central nervous system that can project a perception of the body to conscious areas of the brain. This can easily be undermined, e.g. with strong psychedelic disassociatives such as salvinorins which can brutally alter this sense of self and bodily consciousness through very localised, very specific central receptor action. Another example could be the use of mirror images to treat phantom limbs in amputees. To some it might be frightening to realise one has never been outside a very small part of the brain and never directly experienced anything but projections sent there from a collection of slimy mammal parts that aren't conscious at all.
