2.38.11

tatsannidhānamaraṇānmuktirjantoḥ suniścatā /
ropaṇāt pālanāt sekāddhyānasparśanakīrtanāt /
tulasī dahate pāpaṃ nṛṇāṃ janmārjitaṃ khaga //

From dying in its proximity, liberation of a living being is certain.
By planting, preserving, watering, meditating on, touching, and praising [it],
tulasī burns away the sin accumulated across lifetimes by men, O Bird.
