A perfect Self should be viewed in the context of human biology.
As a “perfect” organ(ism) can exist, serving its purpose with extreme clarity, so can an actualized and/or super individual Self.
Not all of us are meant to be a heart, for instance…
Some of us embody a form whose perfect expression is unique to its duty, as each human’s duty is not identical.
Some people are brains, some are hearts, some are eyes, some are stomachs…
This can be most obviously seen in the ancient caste system, which places this concept into a meta-biological framework, as each caste represents a different part of the human body; each duty not only necessary, but sacred and holy. This was the case within some Indo-European societies all the way into the “Viking Age.”
Like the plethora of circumstances and organs that create a working organism we call a body, we should view ourselves (and humanity as a whole) in the exact same context. We individually make up a greater organism that is called Humanity; where exists many types of organs, tissues, muscles, needs, etc.
Each and every faculty or individual organism has a divine duty specific to their existence, allowing the wheel of human life to move forward in balance and harmony (theoretically).
All things have a meaning and all things have purpose. If this wasn’t so, there would be no cause or reaction; a topic I touch on in this article : Fate, Instinct, and Nature.
Shaping yourself into a potent being should be your main focus, in however that expression manifests within you. Pair this with love and wisdom to achieve the ultimate state of being.
Spend less time thinking of the faults of others and instead set your crosshairs within at your lower impulses and desires; become the spiritual catalyst that the body needs to heal itself and the spirit within.
Narrow your focus on your higher Self. Develop this connection with as much time as you can dedicate to it and you will no doubt find a more solidified presence within yourself; one, that with practice, becomes more and more unshakable.
