I'm not sure if anybody has posted this yet, but you can create an astral temple. And you can go there when you astral travel.
You can create the temple however you want it to be. Just imagine it and keep imagining it down to the smallest detail. Then right before you astral travel imagine going to your temple. I chose a bridge so I could see myself walking down the bridge.
Just imagine your idea of a perfect temple. For me its a pyramid with a bridge leading up to it. Dark clouds around the pyramid and the sun at the top, behind the pyramid. On the inside, there are black and white checkered floors, golden and platinum candles, and giant snakes that guard the temple. If you invoke demons or spirits you can meet them in your temple.
I do this a lot and it is very effective. Make your temple peaceful.
