Krishna consciousness is meant for all-embracing welfare activities for the world

“Just by pouring water on the root of a tree, one nourishes its trunk and all of its branches, fruits and flowers, and just by supplying food to the stomach, one satisfies all the limbs of the body. Similarly, by worshiping Lord Visnu one can satisfy everyone.” Krishna consciousness is not a sectarian religious movement. Rather, it is meant for all-embracing welfare activities for the world. One can enter this movement without discrimination in terms of caste, creed, religion or nationality. If one is trained to worship the Supreme Personality of Godhead, Krishna, who is the origin of visnu-tattva, one can become fully satisfied and perfect in all respects.
