“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 Krishna consciousness. Therefore Krishna consciousness is the greatest benediction for human society.” (Shrila Prabhupada, Chaitanya Charitamrita, Adi 3.97 Purport)
