Mr. Miscavige addressed a large group of leaders from the fields of government, business and the arts. The speech was delivered at Celebrity Centre International. It is known as This is Scientology and is available as a DVD which can be purchased online from Bridge Publications or picked up at a Scientology church or mission.
He covers a lot of ground in this speech, but what Mr. Miscavige specifically says about the questions "What is Scientology?" is this:
Contained in the body of Dianetics and Scientology are answers to those age-old questions — Who am I? What’s the purpose of all this? And, What happens when I die? The direct answers are: You are a spiritual being, distinct and separate from a body. You have lived lifetime after lifetime and will live again. You are seeking to survive for yourself, your family, group, mankind, the physical universe, and to survive as a spirit. And only when you have fully achieved that level of enlightenment can you truly understand the Creator.
And while that may sound familiar to many of you in the tradition of the ancient Eastern religions — you are certainly correct. What is different, and what is new about Scientology, are the means and ways of achieving it. For Scientology is a modern religion, born in the technical age of the 20th century. And if you were to ask any Scientologist, they would tell you it is a practical religion, with practical answers — tools that can be applied to achieve that greater awareness and purpose in the here and now. Or, as we say it, when you have the answers to life’s questions — there is virtually no part of existence it cannot be applied to for the betterment of life itself.
