What are those beads around your neck?
The neck beads that Krishna devotees wear are meant to symbolize submission to God. They serve to remind the person wearing them and those who see them that we are all servants of God, or Krishna.
The beads are made from Tulasi wood (basil plant). Although Tulasi appears in the material world as a plant, she is a great devotee of Krishna. So by wearing Tulasi beads, we please Krishna.
