Sri Krishna will grant the fruit of being the resident of Davarka immediately to those who wear Tulsi beads around the neck.
The sins of the person who wears neck beads made of Srimati Tulsi tree with devotion after offering to Sri Vishnu will get vanquished and Devakinandan Sri Krishna will always remain pleased with him, he does not need to undergo further atonement, no more sins remain in his body.
— His Divine Grace Srila Bhakti Kusum Sraman Goswami Maharaj.
