Many people many minds. Everything in this universe is happening only that there is opposition - opposition in opinion and ideas and principle. When Darwin said that the origin of human being is evolution many came up with arms and tried to contradict his findings. Where Mahatma Gandhi preached non violence others are all violent to solve out any issue that should go in favour of them. Similarly what you feel ok might not be so for many others. The force of opposition is ever on and I feel this is what makes our life worth living.
Do you feel upset when there emerges opposition to your ideas and action?
