All the great realizers, look at what we consider to be negative as something positive. In their state of mind nothing is considered an obstacle, a difficulty or trouble. If we are sick, they teach us to give rise to renunciation. If our back is painful, we should say, “good, keep the mind pure and disciplined”. Pain will help us settle down. It is impossible that we do not have obstacles. Already our karma is very strong, so how should we approach obstacles? If you are sick, give rise to renunciation. If our back is in pain, it will help us calm down. Having pain is good and helps in understanding cause and effect.
