It’s okay when you are first learning to communicate with spirit to set parameters within your comfort level.
When I was first starting, I set the following parameters:
1 - I didn’t want to be woken up in the night by spirit.
2 - I didn’t want spirit to just show up right in front of my face.
Spirit will respect the parameters within our comfort level thus allowing us to lose our fear about the process and gain confidence in our abilities.
