Advaita Acarya saw the entire world to be engaged in activities of material piety and impiety, without a trace of devotional service or Krsna consciousness anywhere. The fact is that in this material world there is no scarcity of anything except Krsna consciousness. Material necessities are supplied by the mercy of the Supreme Lord. We sometimes feel scarcity because of our mismanagement, but the real problem is that people are out of touch with Krsna consciousness. Everyone is engaged in material sense gratification, but people have no plan for making an ultimate solution to their real problems, namely, birth, disease, old age and death. These four material miseries are called bhava-roga, or material diseases. They can be cured only by Krsna consciousness. Therefore Krsna consciousness is the greatest benediction for human society.
