কল্পনার গোল্লাছুটে যুক্তির দরবেশ!

যুক্তিকে বড়ো কাঠখোট্টা ভদ্রলোকের মত মনে হয়। কল্পনা তার বিপ্রতীপে দাঁড়িয়ে থাকা এক অস্থির মতি বালিকা। সে যেন রেবা নদীর তীরে ছুটোছুটি করে খেলছে। আর যুক্তি তাকে বকাবকি করছে। শাসনে রাখতে চাইছে।
অথচ ব্যাপারটা হয়ত একটু অন্যরকম। হয়ত কল্পনা এক বৃত্তে ছুটে চলেছে। যুক্তি সেখানে এক দরবেশের মত এসে হাজির। সে তাকে নতুন পথ দেখিয়ে নিয়ে যাবে আরও উন্মুক্ত অস্থিরতায়। আর আমরা যারা পড়ুয়া তারা মালবিকার মত অনিমিখে তাকিয়ে থাকব পথের দিকে। কে জানে অগ্নিমিত্র আসবেন কিনা!
