I've been following the work of Victor Zammit, and Michael Roll (http://www.cfpf.org.uk) for quite some time now. I am very grateful for these researchers and for the awesome work they are involved and for making their findings available to the world. I also think it is important to realize the enormous contribution made by Arthur Findlay who paved much of the road for the work that is happening right now. Some of his works are: ""The Curse of Ignorance," "On the edge of the Etheric"
