I am into HFA now. Reading as much as I can over the net. Also I have tried using the HFA software and found out that Imaan is dominated by Red i.e. Sycotic miasm. Wish I could confirm this with a HFA trained homeopath.
I am happy that Imaan's new constitutional remedy i.e. Theridion is under the red miasm. See the Grant Bentley's remedy lists here: http://vcch.biz/content/hfa-remedies. However, according to Rajan Sankaran, Theridion belongs to Tubercular miasm. Homeopathy is really complicated and can be very confusing.
Just received Dr. Grant Bentley's book below, and I have placed it on my cannot-wait-to-read shelf. It looks like a fantastic book.
