The Buddha said:
"form is emptiness;
emptiness is form"
That is the view of an enlightened mind. Form is emptiness because no phenomena possesses any self-nature. Everything is interconnected with everything else as One.
The unenlightened do not see it that way. They see form as substantive and distinct from all other forms. What this means is simply that the mind with which the Buddha saw things was a mind transformed by his experience. This transformation of consciousness, or spiritual Awakening, is sometimes called Higher Consciousness, as compared to conditioned mind or Ordinary Mind. The seeming paradox is that Ordinary Mind is the same as Buddha Mind.
I never knew anything was beyond the ordinary mind until I sunk my ship, realized the captain(me) was wrong about everything I perceived no matter how intelligent or good I thought that I was. I went in solitude and silence for 6 months.. no friends, no television, no drama, no nothing influencing me. Everything in life during that time I made no judgements of, only observed. Everything my mind perceived as is needed destroyed and to an empty state, then the rebuilding and radical transformation occurred. Pretty humbling.
You name it, everything.... how I saw and judged others, how I viewed myself and my environment, how I defined "God" or how I defined and perceived everything.... needed empty and clean and swept away. Everything that was impure, I ceased to do. I denied the fire burning within me to give in to many things. Denied all and any thoughts or emotions of what "I" perceived and defined everything to be. The sacrifice of knowledge, thoughts, emotions, perceptions, impurity. . my entire mental worldview had to go.
I even felt the light or energy within me kick on and transform my mind and heart which felt like jolts striking my brain and heart. . rising, ascending, descending within my body back and forth.
Yes, everything is one and there remains no partiality. The experience of complete unity in everything. Ones character and nature is the only thing that will reflect such, how one is with themselves and with others. Ones speech, ones character, ones nature, ones self-control radically reflects it. Intellect or how much knowledge one has of the external universe is irrelevant. It is all knowing and direct experience. It's summed up in three words: "to know thyself." Complete liberation from the external environment of other minds, from being ones own worst enemy, and from suffering.
The Buddah conscious, Christ conscious, super conscious, higher conscious, supreme enlightenment, cosmic consciousness, pure consciousness, supreme awakening, radiant awareness... there have been many terms for it which all mean the same and it's not the meaning that matters, it's the direct experience.
Every human being is always being enlightened in some way, a little here and a little there. That is the fleeting, small tastes and glimpses.
Going all the way to other shore without ending the journey prematurely is where the outpouring and flooding of the light or energy within opens the gates of the mind to the "supreme" enlightenment. Having a crystal clear and aware mind. A pure mind and heart will only see this. The journey never ends, but a radically new mind and heart during the journey of life, with oneself and with others..makes everything so heavenly. That is the eternal, and it also comes with no concepts or rumination of the past, with zero burdens or regret. All is left behind, all is forgiven for the present and road ahead. The new captain of a new ship is smooth sailing. I have little but have everything, and am completely content and fulfilled. The ability to discern, know, and see along the journey.
Even though it's a lonelier journey and road, and one feels like a modern day man living with a bunch of cavemen.... wouldn't trade it for anything. The sacrifices of my own life, my own knowledge and perceptions, becoming self accountable and responsible with no blame, were the initial trade and price paid.
