Hexagrams Options

I was wondering if anyone could tell me why there are different hexagrams in the brh. I know its the hex of fire in the east, earth in the south, air in the west, and water in the north. Im just wondering if anyone could give me some in depth explanations of them, and tell me why there are different ones.

One for each world- Atziluth-Fire. Two masculine triangels (apex up) Since its a world of emations.
Briah- Water. Femanine triangle (apex down) on top of masculine.
Yetzirah-Air.Masculine on top of femenine.
Assiah-Earth.Interlocked Masculine and femenine. The star of david.

Invoced deosil they are still placed in sequence withershins as Hebrew is written from the right to the left
thus forming the name JHVH witch makes up the worlds.

The Hexagrams are traced as if you took the triangels of the original (star of David) Hexagrams and moved the triangels about.
Make triangels of paper with the Sephiroth ascribed to them and place them in the diffrent patterns and you will see where they end up.
