Actor Irrfan Khan who is diagnosed with Neuroendocrine tumour, a rare disease, is currently undergoing a treatment in London.  Irrfan made the shocking revelation about his ill health to his fans through social media in March. 

Irrfan Khan opened up on battling deadly cancer and shared a heartfelt note. The actor has said that the cancer he’d been diagnosed with was rare and had more unpredictability of its treatment. Here's the note Irrfan wrote in Times Of India:

It’s been quite some time now since I have been diagnosed with a high-grade neuroendocrine cancer. This new name in my vocabulary, I got to know, was rare, and due to fewer study cases, and less information comparatively, the unpredictability of the treatment was more. I was part of a trial-and-error game.

I had been in a different game, I was travelling on a speedy train ride, had dreams, plans, aspirations, goals, was fully engaged in them. And suddenly someone taps on my shoulder and I turn to see. It’s the TC: “Your destination is about to come. Please get down.” I am confused: “No, no. My destination hasn’t come.” “No, this is it. This is how it is sometimes.”

The suddenness made me realise how you are just a cork floating in the ocean with UNPREDICTABLE currents! And you are desperately trying to control it. Fear and panic should not overrule me and make me miserable. The entire cosmos becomes one at that moment – just PAIN, and pain felt more enormous than GOD. Nothing was working; NO consolation, no motivation. 

As I was entering the hospital, drained, exhausted, listless, I hardly realised my hospital was on the opposite side of Lord’s, the stadium. The Mecca of my childhood dream. Amidst the pain, I saw a poster of a smiling Vivian Richards. Nothing happened, as if that world didn’t ever belong to me.

This hospital also had a coma ward right above me. Once, while standing on the balcony of my hospital room, the peculiarity jolted me. Between the game of life and the game of death, there is just a road. On one side, a hospital, on the other, a stadium. As if one isn’t part of anything which might claim certainty – neither the hospital, nor the stadium. That hit me hard.

I was left with this immense effect of the enormous power and intelligence of the cosmos. The peculiarity of MY hospital’s location – it HIT me. The only thing certain was the uncertainty. All I could do was to realise my strength and play my game better.

This realisation made me submit, surrender and trust, irrespective of the outcome, irrespective of where this takes me, eight months from now, or four months from now, or two years. The concerns took a back seat and started to fade and kind of went out of my mind space.

For the first time, I felt what 'freedom' truly means. It felt like an accomplishment. As if I was tasting life for the first time, the magical side of it. My confidence in the intelligence of the cosmos became absolute. I feel as if it has entered every cell of mine.

Time will tell if it stays, but that is how I feel as of now.

Throughout my journey, people have been wishing me well, praying for me, from all over the world. People I know, people I don’t even know. They were praying from different places, different time zones, and I feel all their prayers become ONE. One big force, like a force of current, which got inside me through the end of my spine and has germinated through the crown of my head.

It’s germinating – sometimes a bud, a leaf, a twig, a shoot. I keep relishing and looking at it. Each flower, each twig, each leaf which has come from the cumulative prayers, each fills me with wonder, happiness and curiosity.

A realisation that the cork doesn’t need to control the current. That you are being gently rocked in the cradle of nature.

Irrfan Khan also shared a emotional philosophical note on his Instagram account. He had posted a picture of his reflection along with the note.

The post read: "God speaks to each of us as he makes us, then walks with us silently out of the night. These are the words we dimly hear: You, sent out beyond your recall, go to the limits of your longing. Embody me.n Flare up like a flame and make big shadows I can move in. Let everything happen to you: beauty and terror. Just keep going. No feeling is final. Don't let yourself lose me. Nearby is the country they call life. You will know it by its seriousness. Give me your hand #rainermariarilke."
