Shame is a lesson told by society to try to pull up your socks. You have more time to prove that the shame is nothing but a factor helps to gather you together. If you motivate a person through books or seminars, he never reaches his goal wholeheartedly but insults do.
Shame acts as an organiser in you. Shame collects you from the divided you, into one single unit. You want to prove wrong to this world and you are not to be shamed for no other reason in the future. It is a severe pain than losing a loved one or job.
The shame initially pulls you inside and follows you in all walks of your life as a shadow. Shame is a powerful event that will gather power from inside to prove everyone wrong. If you feel shame in your life, I definitely feel that you have proven the world wrong or you are in the process to tell the world in future.
If someone shamed you, you first get humiliated and it lies in the subconscious mind to prove it is wrong. You started to work hard without telling anyone, you became cautious and dedicated human. You pull your resources and do so many sacrifices to prove, to make the shame to feel shame and, the same people will praise you to and that the climax where the shame moves from you to them permanently.
Shame is a powerful weapon you receive from the society for your wrong doing, but it helps to kindle a hero in you and I have seen people who have grown on shame and remain as a good samaritan.
In simple terms,
Shame comes to you when you drop yourself, hence it will make you take back what you dropped and stand as full you in yourself.
