What Is The Basic Cause Of Human Sinful Activities

“Shri Ishopanishad advises us to pour water on the root, the source of all germination. Worship of the mass of humanity by rendering bodily service, which can never be perfect, is less important than service to the soul. The soul is the root that generates different types of bodies according to the law of karma. To serve human beings by medical aid, social help and educational facilities while at the same time cutting the throats of poor animals in slaughterhouses is no service at all to the soul, the living being.” (Shrila Prabhupada, Shri Ishopanishad, 13 Purport)
