People come to the Dharma center for purification, to achieve liberation and enlightenment, so such an easy way to help them is to have a sutra playing so they can hear it as they are resting or working.

You can play the Sanghata Sutra or other sutras. Hearing the sutras can purify not only the ten non-virtuous actions, but also the five extremely heinous non-virtues and prevent rebirth in the lower realms.

It is very good to have a sutra recited by a holy being (such as the recording of Kirti Tsenshab Rinpoche reciting the Sanghata Sutra) so that there is a stronger effect from the blessing of their speech. Or you can have the sutra recited by someone whose voice is enchanting, and who flies like to listen to.
