Based on Bhagavad Gita Chapter 09, Text 21
The power of illusion often makes us mistake the means to be the ends and the ends to be the means.
Even among believers, many get misledby religious materialism. They mistake the things of this world to be the ends and devotion to Krishna to be the means for acquiring those ends. However, our connection with worldly things is temporary, whereas our connection with Krishnais eternal.That’s why the Bhagavad-gita (09.21) points out that those who worship Krishna indirectly for material purposes gain only temporary results at best. Making the eternal, Krishna,a means to the temporary, material gains, is a pathetic underutilization of the eternal.
When Krishna can offer us eternal life, why should we settle for anything less?
To regain the eternal life that is due to us as undying souls, we need to make the temporary the means to the eternal. That is, we need to use the things of this world as the means to render devotional service to Krishna and thus attain the ends of eternal love for him.
