“Krishna consciousness is not a sectarian religious movement. Rather, it is meant for all-embracing welfare activities for the world.”
This is from the Srimad-Bhagavatam 8.5.49
[This chapter of the Srimad-Bhagavatam is entitled “The Demigods Appeal to the Lord for Protection.” Included there is a genealogy of Manus—administrators of the universe—along with a narration of prayers by the demigods to the Supreme Person.]
When one pours water on the root of a tree, the trunk and branches of the tree are automatically pleased. Similarly, when one becomes a devotee of Lord Vishnu, everyone is served, for the Lord is the Supersoul of everyone.

“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 Vishnu 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 vishnu-tattva [personalities of Godhead], one can become fully satisfied and perfect in all respects.
