Unless your vision is constantly the vision of the Divine in all things, you have not only no right but no capacity to judge the state which others are in. And to pronounce a judgment on someone without having this vision spontaneously, effortlessly, is precisely an example of the mental presumptuousness of which Sri Aurobindo always spoke……. And it so happens that one who has the vision, the consciousness, who is capable of seeing the truth in all things, never feels the need to judge anything whatever. For he understands everything and knows everything. Therefore, once and for all, you must tell yourselves that the moment you begin to judge things, people, circumstances, you are in the most total human ignorance.
In short, one could put it like this: when one understands, one no longer judges and when one judges, it means that one doesn’t know.
