Emptiness is not an absence of anything. Emptiness is existence, not nothingness. If emptiness is nothingness, the question is: “Where is the void?” There, it is the void over there.
Nothingness can’t existed among things
Similarly, there are no empty glasses, there is air inside the glass. Even experts began to realize that the vacuum is not completely empty. There are energy fluctuations in it.
An emptiness will be replaced with something else, smaller and softer — transparent.
A particle may be considered as nothing by switching our awareness to a smaller part of it. We saw a book, but now there is no book only particles.
Answer: An empty heart, not completely empty.
Ask: but my heart is completely empty — loneliness.
Answer: Actually it’s not empty, you are not alone — loneliness, there is a sense there, a feeling of emptiness. There is a more subtle feeling, replacing an emptiness, which is a feeling of calm. It’s just that we’re not getting used to be alone — lonely. Our heart gets used to tumultuous in everyday life, then you tried to rebelle to fill your emptiness.
Whereas the heart has been filled with tranquility, it’s just that we are not familiar with this calm sensation, seemed like being detached from reality.
Ask: It’s not like that, my heart is completely empty, even if it is considered there is something, yes it is actually filled with disappointment.
Answer: Disappointment occurs because of this tranquility (looks like “loneliness”) being covered by the thought of profit/loss. If we can keep our heart long enough with the sensation of this tranquility (loneliness — loss — empty), then we will get used to it and realize that our heart is not really “lonely” — not empty, but calm, peacefulness.
Here we will realize/feel/enjoy the truth of God’s word: “Sufficient for me is Allah”
The goodness is “grateful”. The strength of the relationship/closeness is “with love”, while the strength of vigilance is “anxiety”.
And the root of all vigilance, kindness & closeness is “surrender”
