In the Month of September, 1991, I felt blurring of vision during reading, so I got my spectacles checked for refractive errors. The Doctor told me that there were signs of Glaucoma in my eyes. It was a shocking news for me because I knew (being a doctor) that glaucoma is a disease, which decreases eye sight progressively and makes the patient blind. The changes developed in eye because of this disease are not reversible by any kind of operation or medicine I contacted Dr. N. N. Sood, Head of R. P. Center, AIIMS, New Delhi. He was known as father of Glaucoma in India. He got me checked by computerized tests and then he examined me and declared that I was suffering from Open Angle Glaucoma. He advised me to remaining this follow up with him every 2 months, which I did. In 1992 there was first eye and general medical checkup camp in Dera Sacha Sauda Sirsa on December 13th, 14th and 15th. All the devotees who were doctors were called for 'voluntary service' sewa in that camp. So I was also called. On the night of December 11th 1993 I along with other doctors from AIIMS, started for Sirsa by car. On the way I developed clear cut and serious signs of Glaucoma i.e. I saw coloured haloes around the lights of vehicles coming from opposite side. I felt that glaucoma has increased, hence this sign has appeared. I thought that I should contact Dr. N. N. Sood as soon as I return from this camp. After the completion of camp after three days, I straight way went to Dr. N. N. Sood in R. P. center and told about my symptoms to him. He sent me for all the tests in computer room. The technician, who checked me was perturbed on examining my eyes. He went to Dr. N. N. Sood and called him. Dr. N. N. Sood himself checked all tests. On completion of tests he told me that let's have a cup of coffee in coffee room. I was preparing mentally for a bad news. I thought that Dr. N. N. Sood will console me and give some bad news. In coffee room he told me three things: - 1) Dr. Nain since I diagnosed your disease and you are in follow up with me for the last one year, so I cannot doubt my diagnosis. 2) You are also a doctor and we know that Glaucoma is not a self limiting disease. 3) I don't know the reason, but now you are Glaucoma free. As I listened him a strong feeling was generated in me that my Glaucoma has been treated by the grace of Guru Ji during these three days of service in the camp. The stimulus of this thought was so strong in me that I could not withstand it. I drove back to Sirsa to thank Guru Ji. When I reached Dera Sacha Sauda Sirsa, Guru Ji was sitting in Pandal and was meeting Sangat. I met Guru Ji and narrated the whole story from start to end of my disease. How the same doctor, who diagnosed Glaucoma in me and today declared me Glaucoma free. Guru Ji kept on smiling and listening my story. I thanked his holiness for this act of kindness. I could not find words to express my gratitude. Guru Ji told "No, my son I have not done anything, I only showed you a path of humanitarian service. You served the children of God for three days in the camp. In lieu of this service in the camp for three days, God has given you this reward. According to you this disease may be so impossible to treat, but for God, who can give life to the dead person, nothing is impossible. So he has treated your disease. I again thanked Guru Ji and went back to my home. A thought used to haunt me day and night whenever I was in solitude, that if the reward of three days service to the humanity is so high then why I am wasting my time here in government service. After that I started coming regular sewa in monthly Satsang congregation in dera. In July 1995 Guru Ji opened a multispecialty hospital in the remote area of Rajasthan and I joined that hospital after resigning from the government job.
