Why can't the Heart Sutra be hung at home?

It is not good to hang the heart sutra at home, mainly because of the principle of Buddhism. Hanging on the wall is disrespectful to the Buddha, and the heart sutra is enlightened. You should always read it out and be enlightened. The Prajna Paramita Heart Sutra, also known as Mahayana Paramita Heart Sutra, is a concise, profound, comprehensive and extremely important classic in the Prajna Paramita series, which is recited by Mahayana Buddhists at home. At present, the most popular version is Xuanzang's translation.
