That is the material disease. Therefore Caitanya Mahāprabhu says, ceto-darpaṇa-mārjanam (CC Antya 20.12). This roguism has to be purged. Then talk of spiritualism. At heart, dirty things are so much hugely accumulated by millions of years' contamination of this material world. It is very difficult to get out of this roguism. And to become a Vaiṣṇava, he has to become a brāhmaṇa. And brāhmaṇa means... One of the qualification, brāhmaṇa, is, ṣaḍ-laksa (?), ārjava, simplicity. The rogues cannot be simple. Always intriguing, making plan, plotting—these are roguisms. But a Vaiṣṇava requires very simple life. Satya-śama-dama-titikṣa-ārjava (BG 18.42). (someone sneezing) Ārjavam means simplicity. (aside:) He is very forward, without any covering. Now he is sneezing.
Nature's law is so subtle. Uru-dāmni baddhāḥ. Bhāgavata says, uru-dāmni baddhāḥ. Just like a man is tied up tightly, hands and legs, by the laws of nature we are tied up in that way. Every part of our body is being controlled by some controller. We cannot violate a very insignificant portion of nature's law. Kṛṣṇa is perfect. We think that, we rogues, "Kṛṣṇa cannot see." But Kṛṣṇa has kept so many witnesses, and He is sitting Himself within. How you can hide and seek? No hide and seek. That is another foolishness, illusion. How you can hide yourself from Kṛṣṇa? That's not possible. And we are violating the laws of nature, and we are suffering. No excuse. Exactly like that: if a child catches fire, the catches fire will no excuse because it is a child. No. It will act. So we should know that, that... (aside:) Yes, yes. Aiye. There cannot be any excuse. Therefore we have to be very, very careful. And the best carefulness is chanting Hare Kṛṣṇa.
