The material mode of goodness is the most favorable situation from which to move up to the spiritual platform. The Vedas prescribe and forbid various activities to lift the conditioned soul to the material mode of goodness, and from that point he should rise to the spiritual platform by transcendental knowledge. Therefore if one does not come to the platform of Krishna consciousness, his elevation to the material mode of goodness is useless, just as a trip to the airport is useless for one who misses his plane.
