No matter how much you evolve, you are ultimately still in a human body, living a human experience here on Earth. As such, there’s no point in being upset with yourself when you have feelings or when you respond to a situation humanly.
While in human form, there is no point at which we transcend our human emotions — they are an integral part of our humanness. We can, however, become masterful at choosing how we’ll interpret situations and perceive life.
We can create centers of peace and happiness within us, as long as we understand that there will still be times when we are inspired to respond with strong emotion. It is not the experience of the emotion that is potentially problematic, but rather it is how we interpret that experience that can become a source of suffering.
For example, if you respond strongly when your boundaries are crossed (by the same person for the fourth time), as long as you respond from a place of inner knowing (not just a knee-jerk reaction), then that is an appropriate response. But if you then chastise yourself and beat yourself up for being too human, too emotional, etc., then you will create unnecessary suffering.
Instead, I encourage you to reflect on why you responded the way you did. If it was inspired and loving (remember, even firmness can be done in a loving and respectful way), then be gentle with yourself and acknowledge that you responded appropriately. On the other hand, if you realize that you responded from a reactive place (something in you was triggered and you reacted before thinking it through or tuning into your inner knowing), then recognize that you would rather be more thoughtful in your responses in the future.
Ultimately, we are human beings and are emotional creatures by design. We cannot escape our emotions or our humanness. So as you live as a spiritual human, remember that the human part is just as important as the spiritual part.
