Too often the word is not interpreted to its fullest extent. I recall a man reacting to a poster about enlightenment on a facebook post recently. He thought that it relayed a kind of unattainable spiritual hocus-pocus. It was nonsense to him. Of course...his narrow perspective (a common cause of ignorance in reference to any subject), created a prejudice towards the word and what it implied.
I have a different interpretation. To be enlightened is to be aware of things around you. To question and learn. To not take things at face value and mindlessly follow. To be on a constant quest to understand what life is and how it functions. To learn as much as one can while knowing there's always more. To be humble in one's recognition of self and one's place in the universe while exhibiting respect for the Earth, other people and other species. It is having wisdom and knowledge and realizing that each of us is an integral part of the fabric of life.
It is also the ability to welcome discourse. To actively listen to others. To know when to be silent and when to speak. To understand that you may not always be right. To know that people make mistakes. To not blindly believe what you see, hear, or read without investigating further. To not take one's self too seriously. To know the joy of laughter. To revel in being surrounded by family and friends. And...to be at peace, show love, display kindness, and promote learning.
The beauty of enlightenment is that it's available to everyone at anytime. It might seem easy or extremely hard. It may not happen quickly or happen in an instant. It's all in how much you want to open your mind and how much you want to quench you thirst for growth. Enlightenment is powerful. So much so...that an entire age of humanity was named for it.
