Why do we have ventilators in our hospitals? It makes an extension; perhaps a mechanical extension of existence. And therefore it creates an external subsistence. And it gives hope of recurrence and survival. And hope at times gives everything. And your life, liberty and pursuit of happiness are all about that hope.
So, when you are obsessed and persistently double checking things; you create an extended existence of your own alter ego. When you doubt your memories and continuously double check what you have done, like me, you are obsessed too. And no one would ever tell you that; whatever you have done is absolutely well done.
Wherever I walk and whatever I see force me to rewind to the beginning, to double check and to realize, how tiring is this treacherous confusion!
There is a fringe of accessibility in obsession; beyond which no psychic vibration can really answer you, if you ask, am I really gone nuts? And once you infringe the boundary; you would even refuse to ask, am I really sick? And when you realize that you trespass the sacred obsessions; you would forget to ask, am I really a goner already? Rest is freedom. And you realize that you are no longer obsessed and free at last.
And what you need is everlasting peace and prayer.
All praises due to Allah, Lord of all words; The one God to whom praise is due forever.
