Krishna has multifarious energies or shaktis. When people search for mundane opulence in the form of money, fame, popularity, family, pleasure, pain, beauty, intelligence, food, piety etc etc, they are indirectly searching for Krishna through His energy. Because the mundane opulence which is an energy of Krishna derives its attractiveness from the attractiveness of Krishna. So actually it is the attractiveness of Krishna that is perceived within this world and that everyone is attracted to, and eventually searching after.
Why not just directly be attracted to Krishna?
