Animals do not possess a mind like humans. Animals are born today and live for today. But a human being has a special mind. The concept of tomorrow is human mind’s unique feature. All the planning of a human being is based on tomorrow. Without tomorrow, there is no planning, civilization or activity. Unawareness of the world Hereafter leads one to plan only for the present. Seldom can you find a person who plans keeping the world Hereafter in mind. They talk of the world Hereafter, but it is mere lip service, not the result of a deeper realization.
