What an experiment. Proves how we acquire body conscious easily through senses.
Bhagavad Gita says we are not this body but we are soul. In this beautiful experiment, a scientist demonstrets that when we identify that the body is me, then we experience the pains of the body. Since the eyes of the person is identifying the fake hand as his own, the person is feeling the same sensation/pain as real hand. When we realize that we are not this body but we are spiritual soul, that moment we transcend from the pains of this world and pain associated with our bodies. That’s why spiritual people are transcendental to the pain of their bodies & the material world. Hare Krishna
