Tulsi kanthi mala with Krishna's Foot pendent

In Skanda-puran it is stated :- those who wear neck beads made of tulsi after offering it to Sri Hari are definitely foremost among the devotees of Lord. Those fools who wear Tulsi beads without offering to Hari will definitely go to hell. After presenting the mala, it should be purified with panca-gavya; after that the mula-mantra should be recited followed by the recitation of the gayatri mantra for eight times. Touching with incense, worship with this Sadyojata-mantra with utmost devotion.
