Our world can become a spiritual world if we all or at least a large enough portion of humanity is transforming themselfs from egoistic to altruistic creatures and that all those people with the same goal and desire connect to eachother to become a strong force which transforms our materialistic world into a spiritual world
By living according to my understanding of the widom of Kabbalah and by that dissiminating it I really experience it what it means and by that correct my self.
It means that I give up my egoistic and negative thougts about myself and the world and replace them with positive thoughts and bestowal. So changing from thoughts based on fear, lack and resentment to pure love.
When we shift from an egoistic perception of reality to a perception based on bestowal we become more in equivalence of form with the creator and by that come closer to him. We will feel more what it is to be on the spiritual path.
