How to pray for the health of friends?

If your friend's health problems are caused by you, first of all, you should feel ashamed and sincerely repent. 3. You can recite "The Merit of the Drugstore Coloured Glass Tathagata" and return it to your friend with "Nanwu Drugstore Coloured Glass Tathagata". 4. After each reading, the following small directions can be referenced: I would like to repay XXX (your friend's name) with this merit and wish him good health and all the best. 5. Great reward: reciting merits and rewarding all beings in the legal world; Reward four kinds of kindness and help three kinds of difficulties. If you see and hear something, you will learn bodhicitta and try your best to live together in a blissful country. 6. Returning is to return to the small and return to the big, and put the little merits of good deeds into the sea of merits of the Buddha, so that it will not be exhausted. The difference between turning back and praying is that praying turns back before doing good and after doing good.
