Sincerely copy, and return the merits to the ancestors.
It is suggested to copy the original vows of the Bodhisattva, with a total of seven volumes (one is once). The Tibetan scriptures are relatively long, about 20 thousand words. Other classics such as Amitabha Sutra and Infinite Life Sutra are very good. As long as you do it with your own heart, according to your own wishes and according to your own destiny, your ancestors will benefit and cross over. One point sincerely respects one point's interests, and very sincerely respects the extraordinary interests.
