Prabhupāda: This morning we were talking about the sufferers . . . what is called? The sea sufferers?
Devotees: Surfers.
Prabhupāda: Surfer, yes. (devotees laugh) Surfer. I call "sufferer." (laughter) "Sea-sufferer." (laughter) Sea-surfer, it is practical, because we are creating a situation by which we shall become a fish. (laughter) Yes. Contamination. Just like if you purposely contaminate some disease, you must suffer from that disease. Kāraṇaṁ guṇa-saṅgo 'sya sad-asad janma-yoniṣu (BG 13.22), in the Bhagavad-gītā. Why there are different varieties of life? What is the reason? That reason means kāraṇam. Kṛṣṇa says in the Bhagavad . . . kāraṇaṁ guṇa-saṅgo 'sya sad-asad janma-yoniṣu. Prakṛteḥ kriyamāṇāni, prakṛti-stho 'pi puruṣaḥ bhuñjante tad-guṇān (BG 13.22). So the reason is as we are infecting. The nature's law is so perfect that if you infect something, some disease, some contamination, then you must suffer. This is nature's law automatically going on. Kāraṇaṁ guṇa-saṅgo 'sya.
So there are three modes of material nature—goodness, passion and ignorance. So long we are in this material world, puruṣaḥ prakṛti-stho 'pi bhuñjante tad-guṇān. If we remain in certain place, we must be affected by the modes of that place. So there are three modes: sattva-guṇa, rajo-guṇa . . . we have to associate either with the modes of goodness or with the modes of passion or with the modes of passion, er, ignorance. Now, three into three, it becomes nine, and nine into nine, it becomes eighty-one. So mixture. Just like color. There are three colors: blue, red and yellow. Now, those who are expert in manufacturing color, artists, they mix these three colors in different way and they display.
