So many words try to express it: to enter, to awaken, to realise, to reach, to experience ... liberation, realisation, awakening, enlightenment...
And yet, no words can express it, nor can the way be thought of.
Basically liberation has no state. If there were a state, there would be boundaries. Where there are boundaries, liberation can not exist. There is nothing in liberation, no limit, no path, no space, no time. Only emptiness.
