People carry small Buddha statues such as the rubbing, and the Gawu box was created to avoid direct contact with the Buddha statue, just like a Buddha niche. People can also pray for blessings from the Buddha at any time, and when practicing dharma, they can also take it out and visualize it at any time to eliminate karmic obstacles and increase blessings.
In addition to small statues, ga Wu box also contains a small thangka, handwritten scriptures, the living Buddha's hair or monastery blessed barley and so on.
