People suffer on account of sinful activities. There are two things, pāpa and puṇya. So if you follow the path of pāpa, then you must suffer. Just like state laws. If you become criminal, you must suffer. You must go to the prison house. You, you cannot argue that "Why government has created the prison house? Why?" Can you argue like that? Yes, there is necessity. The government knows that there will be some rascals who will commit criminal activities; therefore there must be prison house.
So this material world is prison house. Every one of us, we are member of the prison house—first class, second class, third class, just like in the prison house there are different classes. Duḥkhalayam aśāśvatam (BG 8.15). You cannot expect treatment in the prison house just like son-in-law. No. That is not possible. You must suffer. Otherwise, what is the meaning of prison house? Similarly, Kṛṣṇa says, although Kṛṣṇa has created this world, He says this is duḥkhālayam aśāśvatam, this is the place of misery. And aśāśvatam. You cannot make any arrangement, "All right, Sir, let it be duḥkhālayam. Let me remain here." No. That also you cannot remain. You'll be kicked out. This is the place like that.
