While you're reading this, the electron in an atom has changed its position. Some cells in your body have been replaced, the oceans have lost some water in the form of vapour, the clouds in the sky have moved a centimetre, the trees in the jungle have grown a nanometer, the tectonics plates of the earth have shifted a millimetre, the earth has moved around the sun 29 kilometres, kahi duur universe mein a star is going supernova and at the same time a star is being born in the dust cloud of the remnant supernova. All this happened while you were reading this.
Kehne ka matlab ye hai ki, so many things have changed in the world in span of seconds, fir tumko kyu lagta hai tumhara bura waqt change nahi hoga? Jyaada shaana banke khudke bheje ko shot matt do, bura waqt bhi change hota hai, everything changes, everything is temporary. Bas patience ki baat hai.
