Open minded means understanding more than your self-indulgance in whatever you do first.
Science is self-indulgance, religion self-indulges. people self indulge and anything new is seen as scary. Science and religion are from the same base fear, fear of the unkown and so different criteria for trying to unravel superstition are formulated. One tries to control it via emotions the other tries to control it via logic. both miss the mark big time and whopping gaps happen that are in no way related to the correlation of being open minded. Now the terms of themselves are entities, thought forms that is self-indulgence and its global.
When this collapses it becomes epic like the financial crisis, whopping self-indulgance mind meeds emotions. and the shockwaves resound globaly because the whole system is shut down, not at all open minded to positive ways of being, but selfish and close minded as an entity when it comes to all things that money represents.
Its the same here, everywhere, it is a form of conditioning that limites the use of true power of self purpose, self direction and hence being open minded means not being afraid of anything for there is nothing to be afraid of. It is an illusion created by the mind for the mind. A trap in a box, the reality we live in is good like that, tried and tested without fail.
