Pradyumna: "Sinful activities are of two kinds: those which are mature and those which are not mature. The sinful activities for which we are suffering at the present moment are called mature. The many sinful activities stored within us for which we have not yet suffered are considered immature."
Prabhupāda: Yes. This is also another position. The, the reactions of our sinful activities we are suffering. As soon as we get a material body—it doesn't matter whether a rich man's body or a poor man's, poor man's body—the material body is itself subjected to threefold miseries of this material condition. Therefore Arjuna was advised by Kṛṣṇa: āgama apāyino anityāḥ tāṁs titikṣasva bhārata. You cannot avoid the miserable condition of this body. That is not possible. So we have to tolerate. There is no other excuse. But do not create another body. That is devotional service. Karmāṇi nirdahati kintu ca bhakti-bhājām (Bs. 5.54). Due to our past karma, we have got a certain type of body. Karmaṇā daiva-netreṇa (SB 3.31.1). By the supervision of superior order, superior vigilance, we get a certain type of body. This may be a king's body or a poor man's body, an animal body, or anything, we get. That is by superior order. So we should not create another body. That is the aim of human life. We should not create another body.
Then, another place in the Bhāgavata it is said, nūnaṁ vikarma kurute, nūnam, prammattaḥ kurute vikarma. Prammattaḥ. Prammattaḥ. Pra means prakṛṣṭa-rūpeṇa. Mattaḥ, mad. We are living entities. We have come here in this material world for sense enjoyment, and we are therefore mad after it, prammattaḥ. So nūnaṁ prammattaḥ kurute vikarma. Vikarma means which is against the laws. Just like karma, akarma, vikarma. These are explained. So vikarma means against the law. The Vedic version, they give us that "You should work in this way." But if we do not act according to the Vedic injunctions, that is called vikarma. And we become subjected to sufferings, impious activities. But we do it because we are mad after sense gratification. We do not care. Just like a thief, he knows that by stealing he'll be punished, but still, because he's mad after stealing, he'll do it, taking the risk of being arrested and being harassed. Nūnaṁ prammattaḥ vikarma, nūnaṁ prammattaḥ kurute, yad indriya-prītaya āpṛṇoti. And they are mad after doing all this nonsense only for sense gratification. So Ṛṣabhadeva says, na sādhu manye, "This is not good." Yata ātmano 'yam. "As we have got this body, material body miserable..." Because as soon as you get a material body, you are put into the miserable condition of material nature. So we should not create another body so that we shall be put into, under tribulation again. That is intelligence.
So if we put ourself in the activities of devotional service, we save that risk. Not to create another body. If we do for indriya-prīti, yad indriya-prītaya āpṛṇoti, then we create another body. But if you act in devotional service, then, even there are something, sinful activities, karmāṇi nirdahati kintu ca bhakti-bhājām (Bs. 5.54). So for a devotee, he's saved. He's saved from creating another new material body. In this way, the stress is given that sinful or not sinful, we should not create another body.
