During your spiritual awakening, you may start to feel remorse, guilt or shame over how you have treated people or any reactions you experienced.
You are not going to be perfect, but your purpose is to deal with your Karmic Patterns, which keep you stuck in the illusion.
The observer is the most powerful tool you can use during your spiritual awakening to help you understand your Karmic Patterns.
Think of the observer this way. Everyone has the observer, it is part of you and it isn't attached to anything. It is your higher consciousness.
The observer could care less that you just yelled at the neighbor or cried uncontrollably at the Motor Vehicle Department. The observer is your higher you, it watches and observes without judgement.
It may be hard to comprehend the observer because you have no idea what it means to see something without judgement. Or you have glimpsed the observer, but it isn't always easy to be consistently the observer.
