They communicate through your psychic senses. They live physically in another part of the galaxy, so the god isn't just going to come stepping out of your closet or whatever you expected like that. It's different for everyone how strong their psychic senses are based on things like past lives, but since you are new here your senses are probably very weak. You need to do the meditations and become stronger then it all gets easier. Just be open and trust your instincts trust your soul the gods know how to show you various signs and make sure you notice them. To physically see the god like they are actually in the same room as you is VERY advanced, you aren't going to be that open for a long time. But you will feel their soul like you said you already did and when you are a bit more open you will hear their voice.
