In my view you can not miss the Spirit World.

As Spirit is the Living Essence behind and operating in ALL we see(Matter)
and in ALL we can not see or comprehend.

Separate the changeable from the unchangeable.
Does a Tree express the Spirit of a Tiger?
What does the energy expression say of a thing?
When you drink water, do you have a Spiritual experience with it or do you just pay it no mind?
To many people want to start in the Woo Woo Spiritual.
Watch things operate and you will see the Spirit behind it.
Humans have a deceptive practice of saying and doing one thing
with a manipulative Spirit behind it, but it is always revealed to those how watch.
