A person makes an effort to fulfil those desires which can be fulfilled. But what effort will he make, for those which cannot be fulfilled? Where desires are increasing, the problems keep on increasing, then why should one fulfil them? Then those desires must be abandoned, that is the wisdom. A wise man never fulfills useless or evil desires, they suppress them, discard them or destroy them. If you won’t destroy evil desires then they will suppress or destroy you. Not to arouse desires is the bliss and eternal bliss is true happiness. Those external and false efforts produce many agitations which are done to destroy agitation. Thousands or lacs of desires arise after fulfilling one evil desire. Then they create horrible complications. So not only restrict and limit your desires but along with it destroy them also. This is the path of welfare.
