Tibetan printed prayer roll. The prayer printed is dedicated to the Buddha for atonement of wrong doing by body, speech or mind. There is a passage in Sanskrit which transliterates as, "Namo Ta tha ga ta Buddha Dakhshaya" and translates to, “Homage to all the Buddhas and Boddhisattvas in ten directions”.
This roll, which has been printed with mantras was probably placed inside a hand-held prayer wheel. In Tibetan Buddhism prayer wheels are spun in order to activate the mantras they contain. Whilst spinning the wheel the devotee maintains a focused mindset and may also recite mantras in order to fully realise the merit gained from the spinning the wheel.
