Liber Koth, funky ass Invocations Options

Has anyone here read Liber Koth? I have just finished it and am primed to experiement with the invocations. Does anyone have experience with the Tower of Koth and the mythos entities that lie within?
The whole temple is astrally constructed and so this will be something very new to me.

Heres a link to the book, http://www.amazon.co.uk/exec/obidos/ASIN/1...6570645-9931627

"I have edited this from the previous draft. Hopefully the (in)famous author named is now spelled correctly. I apologize."

Eh? I didn’t read the original so I don’t know what you mean.

"Unlike other animals, insects, fish etc humans have higher cognitive functions"

By this I meant that they have consciousness, but not higher cognitive functions such as sentient thought, to know the concept of 'I' and be able to think, formulate and understand. Fish, Cat's, Rhinos, Wasps etc can't do this, Chimps and Dolphins can, and I would argue that they are sentient, but they still lack the human intelligence that separates us from the rest of the animal world. I believe it was Mr Hyatt that said that man is not a God and he is not a Beast, he is both of them and neither. This is a deep question for philosophy though, and although I would enjoy a debate about it I think that I'm going a wee bit off topic. Maybe in another forum?

I have not yet used Liber Koth, but I am planning too once I know and understand everything there is to know about astral temples and the like, I was never planning to dive in head first. That’s why I was asking here, because I thought someone may have experience or knowledge on the subject and could point me in the direction of a good reading list (thanks bym).

As to why I enjoy the Cthulhu mythos I will go into later, as my philosophy lesson starts in about five minutes and I have to get to the other site lol!
Bye for now.
