Acharya Prashant explains that the word "vulnerability" is generally not likable because it implies the existence of hostile, aggressive, and inimical forces outside of us. This perception leads us to believe we need to protect and defend ourselves with armors and defenses made of thought. We do not want to be vulnerable; we want to be defended. When someone suggests that vulnerability is a virtue, we interpret it as exposing ourselves to attack. However, this view overlooks the basics of duality. You are attacked only as long as there is something within you to be attacked. When there is something to be attacked, you will always feel attacked or threatened. The speaker clarifies that it is not the universe conspiring against you, but rather the self you have built up that lives on a diet of threats. The armor you raise is justified only by the perceived existence of arrows and bullets. It would be foolish to have a thick armor if there were no threat. Because you insist on having an armor, you see only guns and bullets around you. The self and the world are not separate; the moment the armor drops, the bullets also drop. We are scared of vulnerability because we do not understand that the world does not have an objective existence of its own, separate from us. We mistakenly think that we can change while the world remains a wicked place, not realizing that the self and the world are not independent entities. True vulnerability is relaxation. It means that if you are getting hit, what is getting hit deserves to be hit and is being highlighted as the next thing that must disappear from your mind. Getting hurt is a matter of gratitude because it reveals that something within you could be hit. We are already "pre-hurt," like walking bundles of sores, full of wounds and ready to be offended by even a gentle breeze. Vulnerability means not pre-deciding or being pre-hurt. It is to be like a leaf dancing in the wind, responding spontaneously to the moment. The truly vulnerable person is the one who can no longer be hurt.
