मुलांच्या सामान्य ज्ञानात भर पडावी म्हणून हे पुस्तक लिहिलेलं आहे. इंग्रजीत `टेल मी व्हाय’ नावाच्या पुस्तकांची एक मालिका आहे. त्यावरूनच हे पुस्तक लिहिण्याची स्फुर्ती झाली. मात्र शक्य तिथे भारतीय संदर्भ वापरायचे हेही ठरले. पुस्तकास अनुक्रमणिका नाही. कुठेही उघडून वाचावे, अशीच अपेक्षा आहे. मराठीत अशी पुस्तके फार कमी आहेत. त्यात भर टाकायचा हा एक प्रयत्न.
