You rejoice that you have discovered so many delights in the world and that you are living a very happy life, enjoying many things which seem to give you a lot of comfort and joy. But these are not real enjoyments, for, in the future, you will surely have to face the consequences of all these indulgences you are engaging in now. (SBGita)

Do not make the mistake of imagining that the body has been given for enjoyment, comfort seeking, beautification, and useless pursuits of that nature. Indulgence in pleasure seeking, comfort, and luxury can be dangerous. In one of the wars between Germany and France, France suffered a crushing defeat. Reflecting on this, the then French Commander-in-Chief said,  We lost not because we lacked courage but because we had become soft by getting drowned in pleasure-seeking.  You can ruin yourself by pandering to the senses. What does one gain from sensual pleasures? Nothing, because these pleasures are all momentary. God has not given this body for indulgence. (SSB 2000, pp. 68-69)

Man today is subject to more maladies caused by mental worries than by consuming bad food. What is the shape of worry? It is only a mentally created fear. There should be a limit to speculation, anxiety and worries. Otherwise they will lead to mental troubles and derangement. A study of university students showed that 80 to 90 percent of the students in several universities were suffering from one or the other kind of mental disorders. Students should see that, in this most precious stage of their lives, they do not become a prey to physical or mental ill-health. They should keep their minds away from unnecessary thoughts and worries and also avoid excessive reading, playing, singing, and sleeping, etc., because excessive indulgence in any of such activities will have an adverse effect on the body.
