All became Buddha...

"When Shakyamuni attained enlightenment,

all the myriad dharmas [natures] within buddha's mind,

that is, mountains, rivers, grass, and trees, all became buddha [awakened].

All are aspects of buddha.

In this sense,

each and every one of us has been enlightened by Shakyamuni Buddha."
