Buddhism tell us that to attain Enlightment we haveAccording to do some sacrifices in the inside or mind such us letting go of desire, attachment, egoBuddhism, accepting that nothing lasts forever and suffering as part of life and also doing meditation and try to by mindful to live in the now or keep the mind in the present moment as much as possible. Also in the eight-fold path change or existential evolution towards Enlightenment has to do with the outside such as right actions and right livelihood.
Some Buddhists believe that you should not try to change the world but your inner conditions. You should take responsibility for your thoughts and emotional responses. Others say that the inside and outside are one. What happens in the inside reflects what happens in the outside and the other way around. It's clearly accepted that in Buddhism that before you try to change the world you should try to change yourself first.
Example:
A narcissistic millionaire that is never happy and needs to be surrounded by beautiful women and being sucked up by everybody to please his ego who spends billions to build walls.
that's a clear example of somebody who needs to work with their inside.
Another example would be:
An oriental Buddhist girl who is exploited working in a sweatshop" which accepts the world as it is and follows the Dharma no questions asked.
According to Buddhism is it bad for her to try to change her external conditions or perhaps she is encouraged to do so because after all she is taking action for the everybody's well-being? Should Buddhists fight for truth, freedom, justice etc. or that depends on whether you experience suffering(Dukkha)oneself or not? Should we bother aboutchange the external world if it doesn't affect in our way to attain Enlightenment? What's the vision Buddhists, their leaders and their dogma have on this political or external matter?why.
