Even the so-called vegetarians are as much sinful as the non-vegetarians. According to Srimad-Bhagavatam, one living entity subsists on the life of other living entities, either vegetarian or non-vegetarian. But we are neither of them. We are not vegetarian nor non-vegetarian. We are transcendental. We are concerned with God’s mercy or Krishna Prasadam. This is based on pure understanding, not by any sentimental provocation. People must be intelligent enough to catch up this KC movement without being carried away by any sentimental wave. We should always remember that we do not belong to any group like the karmis, jnanis, or yogis. We belong to pure devotional service group, following the footprints of great mahajanas. Our purpose should be that we are in one side and all others they are on the other side. We deprecate everyone, even one who is against animal slaughter. In the Caitanya-caritamrta, it is clearly said that there are two classes of activities. Pious and impious. We do not favor any one of them. Neither we favor any philosophical speculation, we simply stick to God or Krishna, and wish to render loving transcendental service unto Him.
