well I think maybe we dont all recognise them!
For example, my postman just delivered my mail - to the wrong house - next door....because he didnt see the house name....! I pointed it out to him, when he saw it he said, "oh yea! sorry I didn't notice...!"
The point is, people are BUSY! driving, at the bank, getting on a bus, watching TV...these are subtler things....
Another good example is the South American tribe that greeted (sorry I can't remember the names, any historians in the house?) the Spanish, the first time they had seen Europeans, well, they could not see the huge boat afew miles out in the bay OR many rowboats coming to shore until they were practically on the beach! In fact the only person that could was the local shaman - his mind was more tuned in to 'possibilites' than the villagers, it was totally outside their frame of experience that was programmed into their day to day lives, to recognise a huge wooden ship....they had never seen one so did not need to recognise it....Imagine that on a planetary scale.....
I have heard that St Germain as he is the chohan/protector of the purple ray - comunicates with purple flashes....
My recent experience was remarkable in that I had been reading a book about St Germain and after I finished I got these flashes for a few nights/ days after....only maybe for 30 secs at a time on a few occasions BUT - had reading the book made it easier for ole St Germain to get through the veil of my mental rational mind.....?!?

Was he saying yes, the book is correct?
Agree with KELLE BALEY also....
