text: jab main descartes ki famous quote 'i think,therefore i am' ke baare mein sochti hoon, toh mujhe yeh concept kitna profound lagta hai, kya tumne ispe kabhi socha?bilkul! is quote ka matlab sirf sochna nahi, balki apne existence ko realize karna bhi hai, jo har insaan ke liye zaroori hai, hai na?
