Prajna is "wisdom", and Paramita, referred to as "Paramita", is generally interpreted literally as "the shore (the other shore) that has been saved to become a Buddha and free from reincarnation", and the world where we will reincarnate is called "this shore".
"Prajna Paramita" together means "wisdom to save the other side of non-samsara", which is the literal translation, and the free translation is "wisdom to be a bodhisattva". The Heart Sutra is the law of the heart, that is, the basic mentality and conditions that one should have. To put it simply, the "Prajna Paramita Heart Sutra" is the secret of the mind for those who want to become a Bodhisattva and become a Buddha.
The image is made by scanning the 999 gold "Amulet of Consecration". This amulet has been with the author for 40 years. It is because when the author was in his teens, he met someone close to his home as a gift and kept it in his wallet. It took ten years to make this app and give it to the people of the world.
