Emptiness cannot be known. Awareness needs something to be aware of. At some point (words are shit I know) there is a simple knowing that all that can be known is just imaginary and constantly changing relative stuff. It can be something completely different when looked at slightly differently. So it’s just points of view. That’s all. When there is no point of view that remains sticky anymore (needs no more defending, protection or enhancement) there is a strange freedom that becomes conscious perhaps and ‘you’ know ‘you’ don’t exist as such and nor does anything else. All knowing stops there. Finally !! What remains needs no words. Or energy.
