S tairs are used to climb. It is not only difficult but also impossible to reach the top of the floor without stairs. But the main thing is this-that those stairs are also used for going down. The higher you can climb, the more you can go down from the same stairs. Stairs are endowed with both powers. Similarly this human birth is also like stairs. Through these a person can reach not only in the sixteenth heaven but also reach till Sarvartha Siddhi. And if he is a skilled person then he can even attain salvation. That’s why this human birth is better than other births. But don’t forget if you go down the stairs, then you can reach not only seventh hell but also Nigod. So use this life to climb higher (do good works) only then your intelligence will be proved.
