According to the opinion of experienced medical practitioners, diabetes is a result of voracious eating, and tuberculosis is a disease of undereating. We should desire neither to be diabetic nor to be tubercular. Yāvad artha-prayojanam. We should eat frugally and keep the body fit for advancing in Kṛṣṇa consciousness. As recommended elsewhere in Śrīmad-Bhāgavatam (SB 1.2.10):
- kāmasya nendriya-prītir
- lābho jīveta yāvatā
- jīvasya tattva-jijñāsā
- nārtho yaś ceha karmabhiḥ
The real business of human life is to keep oneself fit for advancement in spiritual realization. Human life is not meant for making the senses unnecessarily strong so that one suffers from disease and one increases in an envious, fighting spirit. In this age of Kali, however, human civilization is so misled that people are unnecessarily increasing in economic development, and as a result they are opening more and more slaughterhouses, liquor shops and brothels. In this way, the whole civilization is being spoiled.
