Tom Cruise and Nicole Kidman’s adopted daughter Isabella Cruise has thanked the Church of Scientology for providing the missing piece in her life.

Isabella is currently undergoing training to be an auditor and explained that she was “drowning in problems” before being able to qualify for the role.

In a post published to an anti-Scientology blog called The Underground Bunker, Isabella reflects on her intensive training.

“It turned out it was exactly what I needed,” Isabella wrote.

“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.”

As Isabella is now an auditor, this means that she is able to guide others through the process of being inducted into the church.

This includes using a lie detector, which is referred to as an e-meter, to rid new members of negativity.

Isabella is thrilled with her new position and encouraged others to join.

“It’s a few meltdowns 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,” she explained.

“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.... So stop messing around and get going.”

She also credits her father, Tom Cruise, her aunt Cass and other members of the church for helping her get through the tough times.

“Thank you to my Dad for everything,” she wrote.

"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.”

Isabella is the  daughter of Tom Cruise and Nicole Kidman, who they adopted in 1992.

They also adopted her younger brother Connor three years later in 1995.

Tony Ortega, who shared the email online, has said that this is a big deal for the Church of Scientology.

He told Sun Online: “I have never seen a celeb (even a minor one) do a promo for 'training' – the work to become an auditor.

“This not only shows that she's dedicated to the church, it reinforces that Tom is fully on board, and it suggests to rank-and-file members that the famous members are behind Scientology leader (David) Miscavige and they should be too.

“Now that she's trained as an auditor, she'll be able to do the questioning involved in auditing, which means, she'll be helping others plumb the depths of their pasts to discover the secrets that are holding them back.”
