Fatness, thinness, bodily and mental distress, thirst, hunger, fear, disagreement, desires for material happiness, old age, sleep, attachment for material possessions, anger, lamentation, illusion and identification of the body with the self are all transformations of the material covering of the spirit soul. A person absorbed in the material bodily conception is affected by these things, but I am free from all bodily conceptions. Consequently I am neither fat nor skinny nor anything else you have mentioned.
