COVID-19, caused by the SARS-CoV-2 virus, has resulted in nearly 7 million deaths globally as of 2023 and remains a significant health challenge. Many patients continue to suffer from long-term complications, commonly known as "long COVID," for which no definitive cure has been found. This has prompted a surge in research on potential underlying mechanisms of immunity. In addition to scientific advancements, holistic approaches to recovery are gaining attention. This study explored the application of the Guan Yin Citta Dharma Door, a Buddhist practice, in addressing both COVID-19 infection and its post-infection sequelae. By presenting a case study using this method, we examined the role of karma and collective retribution in the manifestation and healing of COVID-19. The findings suggest that integrating Dharma practices may complement conventional medical treatments, providing a holistic path to recovery for COVID-19 survivors.
