A vessel cannot remain empty, women’s womb cannot remain empty, land which can flower cannot remain empty and time at hand cannot remain empty. We pray for ourselves. We wish for betterment. Wishes should be fulfilled or man will struggle to make it true. There are men who believe in worldly actions. They have sole purpose of filling up the vessel. The men beyond the boundaries of acceptable actions are ascetic, or sadhu (maybe from sadha meaning plain/ tasteless). He is a person who is in process of renunciation, trying to empty his physical being.
Western philosophers had always associated emptiness with negative depiction of god, mostly reinforced by christian theology of creating as means to fill the nothing with things and nowhere as a space.
As Heidegger said
The fact that what is threatening is nowhere characterizes what Angst is about. Angst ―does not know‖ what it is about which it is anxious. But ―nowhere does not mean nothing; rather, region in general lies therein, and disclosedness of the world in general for essentially spatial being-in. Therefore, what is threatening cannot approach from a definite direction within nearness, it is already ―there – and yet nowhere. It is so near that it is oppressive and stifles one‘s breath – and yet it is nowhere. In what Angst is about, the ―it is nothing and nowhere‖ becomes manifest (Heidegger 1963, 186; Stambaugh 1996, 174-5).
I ask you something, can nothingness be a reality or is it just experience. If it is nothing, can it be felt.
Indian yogic philosophy orders the existence of universe into suksham (miniscule), stula (matter), shunya (nothing) and shiva (god). For yogi, it is the ladder to reach the god. For he had realised that universe is nothing larger as your fist. He will scrounge both inside and outside, to experience the nothingness. An means ‘not’and Anu means ‘atom’. And Rutherford found out centuries later, that most of the atom is in fact empty.
