New Delhi: "Tiger hai tu, tiger.

Roar roaaarr!" Remember these words from Sanju Ranbir Kapoor and Vicky Kaushal made us secretly weep in our recliners as they brought alive the real-life rapport between Sanjay Dutt and his best friend Paresh Ghelani on screen.

For the big screen adaptation, US-based entrepreneur Paresh Ghelani's character was named Kamlesh/ Kamli and was played by Vicky Kaushal.

Now, the real-life Kamli AKA Paresh Ghelani is making us well-up again with his heart-wrenching thank you note to Sanjay Dutt.

In a lengthy note on Instagram (his account is unverified), Mr Ghelani wrote: "Sanju, thank you for being a part of my life.

Thank you for making me part of the pride where we watch each other's back; Thank you for always having the protective blanket over me; Thank you for the journey you've dragged me on lovingly and have taught me how to fight the adversity, however it may come."The recently release Sanjay Dutt biopic reveals Paresh Ghelani was one of the strongest driving forces in the actor's life, who helped him overcome drug abuse, deal with the loss of his parents and several other emotional upheavals.

Now, here's what Paresh Ghelani has to say about the biopic.

"After watching the film Sanju, I was numb, numb with limitless emotions.

I wanted to just hug him, hold on to him and cry.

Cry endlessly to the years we had lost, to the years we stood by and witnessed this roller coaster called life and the irrevocable loss of loved ones To the mistakes we cannot undo, to the strength we cannot find elsewhere but, in each other."Addressing Sanjay Dutt, he also added: "Our friendship has been exhilarating, volatile, wild and rewarding Our journey has often been clouded in disbelief and doubt, wondering if we will make it till the end or will fall into the labyrinth of tragedy and controversy.

But here we are united, unbreakable and ready for life." And we loved the way Mr Ghelani rounded off his post: "Keep roarrrrring tiger," he wrote!Read Paresh Ghelani's full post here. its been many years of staying away from the social media, i finally give-in to embrace it.

as i begin, here to you my brother @duttsanjay.

After watching the film 'Sanju' I was numb, numb with limitless emotions.

I wanted to just hug him, hold on to him and cry.

Cry endlessly to the years we had lost, to the years we stood by and witnessed this roller coaster called life and the irrevocable loss of loved ones..

To the mistakes we cannot undo, to the strength we cannot find elsewhere but, in each other.

Now, the entire world shares our story, and the story of the man who's made me a part of his and he has thought me how to get up after every fall.

It's hard to convey how many different emotions I'm feeling at this time.

How many of us can truly say that we've got friends who not only stand by you through thick and thin, but are as much a brother, a mentor, and your live conscience Sanju, you have been all that and more.

There were moments I've relived from my own life - things I've forgotten, and things I'll never ever forget - on screen.

Sanju is an ode to falling, rising, making mistakes and learning, flaws, imperfection - everything that defines the core of friendship.

It is more importantly a relentless pursuit of life with all its shades.

I know I share this sentiment with all friends and family close to him.

Our friendship has been exhilarating, volatile, wild and rewarding..

Our journey has often been clouded in disbelief and doubt, wondering if we will make it till the end or will fall into the labyrinth of tragedy and controversy.

But here we are united, unbreakable and ready for life.

Sanju - Thank You for being a part of my life.

Thank you for making me part of the Pride where we watch each others back; Thank you for always having the protective blanket over me; Thank you for the journey you've dragged me on lovingly and have taught me how to fight the adversity, however it may come.

Look past the flaws, the women, the controversies, I love you, and now I can share it with everyone.

You always have been, you are and you always will be the greatest friend, brother that anyone can ask for.
