Hi
Could you try and write the parts in bold in your own words so as to make them clearer to me? Actually, I suppose, that I understand everything or almost everything, I'm just curious how to say the same, but in simpler terms.
1. Most divinatory systems contain some sort of element of "chance."
This determines which tools - in this case, stones - will be available to help us unlock the secrets of tomorrow. Pulling a stone at random from a bag, shuffling tarot cards.......
2. The future isn't predetermined. If you see something that bothers you, change it through magic!
If an unreasonably rosy picture is presented to you, you might question yourself: am I reading my desires into this? Am I properly utilizing the system? Is this system appropriate for me? (In other words, does it speak to my psychic mind?)
3. Part two (of this book) can be read
straight through or used for reference as you discover new stones.4. Obsidian is effective when carried or used in protective rituals. One involves surrounding a white candle with four obsidian arrowheads that each point to one of the directions.
This sets up aggressive energies that guard the place in which it is set up.
--- How is that possible that "aggressive energies" can guard???
That's it for the time being. I suppose I will have more later on

Thanks
