First of all, Buddhism does not object to sick people going to the hospital for treatment, taking medicine, giving injections and even performing surgery. It is also a kind of suffering, so it is also a process of eliminating karma, depending on the change of the mentality of the parties.

Of course, while receiving hospital treatment, it does not prevent us from using Buddhism to solve some problems in our reality. Specific to the landlord's situation, the simple way is to recite "there is no Guanyin Bodhisattva in the south" or "there is no Amitabha in the south" and pray for the mercy and blessing of the Buddha and Bodhisattva, so that the evil cause of the disease can be far away as soon as possible. In addition, some release activities can be carried out with the force of fate, which can help.

Tell me a little about my own experience. It may be very effective to worship Buddha more. By worshipping Buddha, the meridians on the body can be unblocked, the temperature of blood can be raised, and the cold on the body can be driven away, which is very effective for diseases such as rheumatoid disease.

Cross your hands and wish good luck, Amitabha.
