every is addicted to except devotees

In this material world people are engaged in different activities simply to achieve a little success in sense gratification. The karmis are engaged in performing very difficult activities, and thus they open gigantic factories, build huge cities, make big scientific discoveries, etc. In other words, they are engaged in performing very costly sacrifices in order to be promoted to the higher planetary systems. Similarly, yogis are engaged in achieving a similar goal by accepting the tedious practices of mystic yoga. Jnanis are engaged in philosophical speculation in order to gain release from the clutches of material nature. In these ways everyone is engaged in performing very difficult tasks simply for the gratification of the senses. All of these are considered to be engaged in sense gratificatory activities (or visaya) because they all demand some facility for material existence. Actually the results of such activities are temporary, as Krsna Himself proclaims in Bhagavad-gita: antavat tu phalam tesam: "The fruits [of those who worship the demigods] are limited and temporary." (Bg. 7.23) Thus the fruits of the activities of the yogis, karmis and jnanis are ephemeral. Moreover, Krsna says, tad bhavaty alpa-medhasam: "They are simply meant for men of small intelligence." (Bg. 7.23) The word visaya denotes sense gratification. The karmis flatly state that they want sense gratification. The yogis also want sense gratification, but they want it to a higher degree. It is their desire to show some miraculous results through the practice of yoga. Thus they strive very hard to achieve success in becoming smaller than the smallest or greater than the greatest, or in creating a planet like the earth, or, as scientists, by inventing so many wonderful machines. Similarly, the jnanis are also engaged in sense gratification, for they are simply interested in becoming one with the Supreme. Thus the aim of all these activities is sense gratification to a higher or a lower degree. The bhaktas, however, are not interested in sense gratificatory practices; they are simply satisfied to get an opportunity to serve the Lord. Although they are satisfied in any condition, there is nothing they cannot obtain because they are purely engaged in the service of the Lord.    (More...)
