Tamāla Kṛṣṇa: "One who seeks an improvement in health or aspires after material . . ."
Prabhupāda: Generally this yoga practice goes on in the name of improving health. Somebody goes to reduce fat. You see? Reduce fat. Because you are rich nation, you eat more and become fatty, and then again pay yoga practice fees and reduce your fat. That is going on. I have seen some advertisement the other day, "Reduce your fat."
Why you increase your fat? The nonsense, they will not understand that if I have to reduce it, why I increase it? Why not be satisfied with simple foodstuff? If you eat grains and vegetables and light foodstuff, you'll never get fatty. You see? You'll never get fatty. Reduce eating as much as possible. Don't eat at night. Practice yoga like this.
If you become voracious eater, you'll be . . . there are two kinds of diseases. The voracious eaters, they are attacked with diabetes, and those who cannot eat sufficiently, they are tuberculosis. So you cannot eat more or you cannot eat less. You just eat what you require. If you eat more, then you must be diseased. And if you eat less, you must be diseased. That will be explained. Yuktāhāra-vihārasya yogo bhavati siddhati (BG 6.17).
You are not to starve, but don't eat more.
Our program, kṛṣṇa-prasādam, is that you eat kṛṣṇa-prasādam. Eating is required. You have to keep your body fit for any practice. So eating is required, but don't eat more; don't eat less also. We don't say that you eat less. If you can eat ten pounds, eat. But if you cannot eat ten pounds—out of avarice, out of greediness if you eat ten pounds—then you will suffer. You see? So here is the . . . what is that? "No material facility."
