What does it mean to become one with nothingness?
Actually, there was a time when no creation, no beginning, nothing existed. Every rule, every law, every creation was born out of nothingness. Nothingness existed before the absolute beginning and it will exist after the extreme end.
When that person became one with nothingness, it can be said that now nothingness was his existence. He was above everything, every creation, every rule, every beginning, and every end.
He was nothing yet he was everything!
He is the beginning and end, he is the Yin and Yang, he is the creation and destruction, and he is the past, present, and future.
There is nothing hidden from his own eyes. He witnessed everything. He witnessed the first creation ever. He witnessed the last existence disappearing into nothingness.
Now, the past was him, and he is the future.
There was a time when everything truly began.
"So, this is how it looks when there was nothing!"
