Srimati Tulasi Devi is Bhakti Devi, so we must be very careful to worship Tulasi Devi. Darshan (to see), Sparshan (to touch), Dhyan (to meditate), Rupon (to plant seed), Sechan (to give water), Pujan (to worship), Parikrama (to move around Tulasi Devi) etc. seva of Tulasi Devi can give you Bhakti – if done with full care & respect. The great Namacharya Srila Haridas Thakur used to do Tulasi puja & Harinam. If you can maintain both eternal & external purity then you can get great result shortly. Try to offer water, flowers, garland, dhupa, dipa etc. to Tulasi Devi both in the morning & evening time. At veranda or at rooftop or at any open place where sufficient air, water & sunlight facility available, there you can keep Tulasi Devi. Or you can make an altar for Tulasi Devi. Time to time cutting of Tulasi Manjari can help the growth of the tree. But always try to protect Tulasi Devi from too hot or too cold weather. Don’t try to touch Tulasi Devi in an impure condition. Only after taking bath & changing cloth you can worship Tulasi Devi. Tulasi leaf can be offered unto the Lotus Feet of Bhagavan with great care. While taking a leaf from Tulasi tree you must beg for pardon. I can say this much at present.
