Communicate

There is one particular way that you can invoke Thor, the god of thunder Himself.
Hold a Mjolnir and visualise a Mjolnir. You need to be alone, with a quiet space, and not be disturbed by anyone or anything. Unplug the TV, switch off the phone, and shut the doors and windows. It can be during night or day. Strongest during a rain and even stronger during a thunder storm.
You can speak out loud or whisper, He can hear you.
You also have to believe in Him and if not, forget it. You need to make sure that you are sat comfortably. You have to feel relaxed in your own choice of setting, be it a room or outdoors. Make sure that you don't feel upset at the time, for instance, if you have a tummy ache, or dislike the smell of oil and sat around dirt. You need to be totally calm, relaxed, at peace with where you sit.
You're allowed to have pets near you so long as they don't play up.
Visualise the Mjolnir in your mind and close your eyes. Imagine the Mjolnir as being made of light, or golden. Once you've done that, still holding your own Mjolnir in your hand, visualise that you touch this imagined Mjolnir and it feels hot.
You may even flinch at the heat. If so then you're at a level now where you are able to send your message.
You can talk to Him. You can ask for His guidance.
Once you've finished, thank Him for listening to you. Open your eyes, let go gently of the Mjolnir and at ease get up and do your normal things, switch the TV on, switch phone on, and have a drink. Do anything that's part of your day to day ritual. Or continue to read a book, have a bath, go for a drive, hang out with friends, go to bed, whatever.
Over the course of the day, look for any special clues that relate to Thor.
If you find any, or recognise it, that's Him sending you symbolic messages.
