According to psychology, self-concept is the perception a person holds of themselves. Self-concept is how an individual perceives their characteristics, worth & value, persona, roles in society, and self-esteem. There are a couple of branches to self-concept: Self-image, self-esteem, and self-actualisation. These are usually developed from a very young age where kids are exposed to life experiences, environments, and family members that impact our belief system.
As we understand from the law of attraction, we attract what we are, not what we want. Whatever we are embodying is what we attract into our reality. According to Neville Goddard, a spiritual teacher, he explained that everyone is us pushed out, therefore, people perceive us the way we view ourselves. People treat us the way we treat ourselves or how we think we deserve to be treated.
Self-concept is the foundation of manifesting ANYTHING. Our beliefs about money, employers, spouses, exes, in-laws, coworkers, life, love, and relationships are created all around us all day every day. The foundation of a house has to be a solid one in order to stand firm and still regardless of what happens in the physical world. We respond to the world and our circumstances from the state of being and the self-concept we are embodying.
On the other hand, we have seen many people who have a poor self-image experience a loving, healthy, and stable relationship. This shows that a belief is powerful enough to counter any situation or circumstance. You can feel low about yourself and have the partner of your dreams, money, and a job. Though that is NOT always sustainable. The point of spiritual awakening is to understand that your true essence is love and oneness. Everything else is secondary. The key here is to master yourself and your self-concept to remain stablised and fulfilled from the inside out. Many relationships come to an end due to personal insecurities that cause a lot of arguments and unhappiness.
In a summary, your manifestations are unconditional until you decide that you cannot have something till you master your self-concept. However, self-concept work is crucial for lifelong inner peace and happiness. Self-concept is what allows you to have sustainable results with manifesting and to truly enjoy your desires when they materialize.
