This is a group of people that are interested in Self-Improvement either busy with it already or willing to do something in this field.
Adding the following to be safe:
The main organizer of the group, Puneet Dhamija, one of the most friendly people you will ever meet, is a Scientologist, though born in a Hindu family and studies various believes and practices including Buddhism, Bahai, etc. to name a few, he shares the knowledge that he has learned at the Church of Scientology, the place, where Scientologists attend educational and spiritual classes and seminars. A Church of Scientology is open to all denominations, including non-believers.
Most of the meetups on this group will take place at a museum - L. Ron Hubbard House / Heritage Site/museum that is dedicated to the founder of Scientology, L. Ron Hubbard.
A Church of Scientology and the above museum are two separate entities, yet, they are affiliated to each other as the managers of both organizations are Scientologists.
