Discussion on technology and how it could be used to assist spiritual development and NOT enslave us. This includes technology that will help us live in harmony with Nature (e.g.: "Lifter" technologies that could replace the petrol driven engine). Also, discussion of past and current scientific thought so that gems are not buried in the sands of time, and spiritual progress through science is achieved.
