Pleroma is a noun that refers to a state of perfect fullness.
Coming directly from the Greek word that translates into ‘that which fills,’ pleroma has been with us since the mid-18th century. It may be used in a religious context or in a more secular sense, for example:
That glass of lemonade wasn’t just good. It was perfection itself. I would even go so far as to say it helped me reach a state of pleroma.
