Tom Cruise's daughter Isabella has penned an essay for a Scientology publication, thanking her dad for introduction her to the religion that she says is "exactly what [she] needed."

The letter to church members was first posted by former Scientologist Tony Ortega. The 26-year-old adopted daughter of Cruise and his ex Nicole Kidman worked as an intern performing "audits" on church members. The system involves connected someone to an E-meter to read what's bad about their personality, hindering them from happiness and success.

She wrote:

    "WE ALL NEED TO DO THIS.

    Wow. What an accomplishment.

    I’ve written this success many, many times over in my head. I want to get it just right. But now that it’s time and I’ve forgotten many of my mentally penned notes, here comes the real one.

    This journey started with my training, and even that was a bullbait. I knew I needed it but every fibre of my being fought me on it. Said I was the PC, that if I did it I’d get nothing from it and many more delightful little criticisms. I was overwhelmed before I started.

    Finally I got through that and what a ride. It was incredible but I was BIs at the end. I had gotten SO much out of it but there was something missing and it really was messing with me. Hard. I couldn’t figure out what it was.

    The next thing was internship and lord knows I was not into it. I tried to get into it but it was even worse than the training. I had so many reasons and excuses as to why I didn’t need to do it and how it just wasn’t right for me.

    It turned out it was exactly what I needed. I dragged out the testing and correction, just made it through the drilling and then finally began my auditing adventure, and wow, I wasn’t prepared. This IS what I had been searching for. The missing piece. Suddenly everything began to make sense. My metering… Wow. It became clear I actually knew my metering. Even to the point of having any slight doubt on a read. I know it wasn’t a read. Beautiful thing about drilling, of course. The tech that I felt was wavering and on the verge of disappearing from my mind became part of me. I know it. Like really know it to the point that it’s just there man. I never thought I could know something like that.

    I became that annoying girl in the org who would just talk endlessly about how incredible training is and how phenomenal the internship is. I’m sure a few people couldn’t deal just like I couldn’t. But I won’t stop with that because now I KNOW.

    We all need to do this. It’s hard work. It’s a lot of effort. It’s a few melt downs and running to the bathroom to have a mini episode, but it is worth everything because you will get through. This is a gift to yourself and so many others. It doesn’t matter if you aren’t going to be an auditor or aren’t going to join staff. If you are going to make it as a being for the long run you NEED this. That’s the truth. You won’t stay Clear or OT without it. So stop messing around and get going.

    The internship, for me, is what made me a Scientologist. I don’t just believe the tech works now. I know without any doubt that it does.

    Thank you to my Dad for everything. To Cass. To Tash. I would have drowned in my own problems if you hadn’t been there to sup me or get me through the preliminaries. And every other single person from the C/S to the Qualifications Sec, who has taken even just a minute of time to help me get through. It took a whole family and org to get me here. So thank you to all for the endless support. And to those who saw me in my moments. Thank you for seeing me to the end. This isn’t just my product but yours as well.

    Thank you to COB. This wouldn’t be here without you. I can’t even begin to describe. It would take me a few centuries.

    Thank you to LRH, on so many levels. I’d need another few centuries to even find the words.

Cruise thanked church leader David Miscavige and L. Ron Hubbard for her happiness. So far Tom Cruise has yet to speak publicly about the letter but the actor has been perhaps the main supporter of the church over the past two decades.
