Without understanding the philosophy of Krishna Consciousness, if we try to convert Christians into Krishna Consciousness, it will be utter failure. We do not condemn any religion because the Bhagavatam says that the religious process is the best by which one can attain love of God. So we are teaching Love of Godhead, not any particular type of religion. Our Krishna Conscious movement is not a religious movement; it is a movement for purifying the heart. Modern civilization is defying the authority of the Personality of Godhead; the more a man advances in his material adventures, the more he becomes covered by the illusory energy.
This conception that when one's material concept of life is finished, the material vision of this also vanishes. Actually there is one energy of Krishna, which is spiritual. Material consciousness of life means forgetfulness of Krishna; when one is fully Krishna Consciousness, there is no more any material existence in the vision of such advanced devotee. We have to learn it step by step; just like we prepare prasadam, and ordinarily it is rice, dahl, and capatis. But when it is offered to Krishna, it becomes prasadam. How ordinary rice, dahl, and capatis turns into spiritual prasadam is to be understood by advancement of Krishna Consciousness, but actually anything in relation with Krishna is spiritual energy.
