There is one further need that Maslow didn't mention. Though he probably intended it to be included as a self-actualization need, really it deserves its own category. This is:
It is only by having at least a glimmer of this spirituality that we each are part of, that we can aspire to the highest potential of being human. To be able to genuinely love and to forgive unconditionally, we need to see in all others - even our enemies - the same essential quality that we ourselves are part of. Spirituality is a transpersonal quality, it is beyond the ego and obsession with the self. It is the maturity of intuition.
The path of personal transformation is primarily a process of becoming aware of, facing up to and taking responsibility for one's thoughts, feelings and actions, and then expanding this self-realization by communicating with others, retaining integrity whatever the response, and further enhancing the quality of communication with ever-increasing empathy and understanding. Through understanding others better, we can recognize their essential goodwill, however misguided it might have become, and begin to recognize the spirituality of humankind.
But first we need to know ourselves better.
The psychologist Nathaniel Branden developed a technique called Sentence Completion, to help his clients uncover and communicate their true feelings, that previously were suppressed. This denial of feelings and true wishes or desires occurs because of fear that acting on them or communicating them will bring scorn or ridicule - in short, will upset the apple cart. But to continue suppressing what one truly wants is to die inside, to lose integrity.
Try completing the following sentences, with as much honesty and frankness as you can muster. Move on to the next one when you have uncovered an awareness that you were previously suppressing. And then put this self-realization into action in your life.
