This is a post that is very deep. It requires so much deep thinking to be able to fully understand the message. In my opinion, I feel some of what we call 'curses' are beliefs and behaviours that we inherited that we allow to shape our mindset and the choices (decisions) we make in life.
Like you have rightly opined that awareness is very important. We have the power to rewrite our own stories with prayers, strong mindset and doing the right things.
