Why the quality can't be totally finished in upper world? What does the reason, please?

Swami replied:- Can you give the answer for the same question in the case of a thief here punished in the police station or sentenced to the jail? The total change is never possible through punishments, which can only reduce the vigour of the bad quality. This does not mean that this problem has no solution since God wants continuous entertainment. If the quality is totally changed, the recycle of the creation becomes impossible and hence, it is the wish of God to arrange the system like this for the sake of His selfish entertainment continuously. Such idea is wrong. The divine spiritual knowledge brings total change in the quality. In fact, God comes to this world for this purpose only. A little co-operation from the side of the individual soul is also required, which is to receive the divine knowledge seriously. In this way, there are examples of total transformation as in the case of Valmiki, a hunter, changed by the sage Narada. If the doors are totally closed on all the sides, we can blame the God. The Gita says that you can cross all the sins by entering the boat of spiritual knowledge (Sarvam Jnanaplavenaiva) and also says that the spiritual knowledge that brings total transformation in you can also burn even the balance unpunished also (Jnanaagnih...). The reason here is that the aim of the punishment is only to bring the transformation, but, the punishment brings only temporary reduction of the intensity of the sin, whereas knowledge brings total transformation. Then, you may ask that in the upper world, let the knowledge be taught instead of the punishment! My question is that why don’t you do the same in this world also removing the police and jails? The point here is that the punishment given is totally from the side of hell and there is no need of any co-operation from the side of sinner. In the transmission of knowledge, the co-operation from the soul’s side is also needed. The current is transmitted in conductor but not in insulator. In the case of such insulator, punishment alone is left over remedy. At least reduction of the intensity is better than no change in the intensity.
