There are two main reasons why chronic diseases happen. 1) You can't leave things on time and move on.(Ketu) 2) You don't know where to stop.(Rahu) When you cannot resolve an internal conflict between mind and soul, you are making a small knot in your system, and over time, your disagreement on various matters will increase slowly. This disagreement will take the physical form of a tumour, and you will rush to a doctor, where most of the time Doctor will suggest you get it removed immediately as this is life-threatening. Before you decide your beautiful body to go under the knife in the unconscious state, think your present condition has not happened in a day, and even if you try to get anything removed, it will still not be over as this is how cancer cells are, You might remove the physical tumour, but the cause due to which it occurs stays pretty much in the body. After 3-4 years, it will again come back as you have not corrected the root cause of it. The conflict your soul will carry to the next birth and will trouble the new body as well; it is better to resolve conflict, and you will see tumour slowly will also start to get resolve; what has built over a time period of 2 -3 years will not be resolve in 2 weeks, but over a period of time you will see results. Learn to let it go during pitapaksh, grudges, and hate; you are holding a burning coal in your hand to throw at someone, you might be able to fit a few, but in the end, it is your hand which will suffer most. Keep doing good for people even when you get hate, as people can only give things they hold. The world is never ready for people here to give, as that is googly for those thinking of themselves only; keep doing good and don't complain; let the universe take care of everything else. Stay blessed in this magical world.
