The entire concept of thinking in the article is kind of wrong. If we ask again what is mindfulness technique and what is created for, we will arrive to answer that it is technique from Buddhism, meant to liberate us from world, and repeated cycle or rebirth and suffering. Regardless of what you believe pause there and ponder. Forget for a moment whether you believe in after life or not. If we think about the end goal "liberate from the suffering" liberate from world and minds game. So, we took a tool which should liberate us from world to become more productive? Isn't our usage premise wrong? Of course there will be side effects, if you "abandoning" everything that is world game and keeps you worried or money looking animal, why is so strange that there are side effects as selfishness? First stage of going inward is removing everything around you, and by seeing true nature you stop caring. But by stop caring suddenly, you see that as explained in many scriptures 'good or bad do not exist' there is only constant change. Imagine you are child and you are with other children playing in the court, they ask you to join and you refuse. You say "I do not want to be in the game", and they reply "Why not?! C'mon we need extra player, here, you can be on a good side", you reply "I do not care about game, sides, manipulations, or you, in fact in this moment I do not exist"... from your perspective this is valid, from other children perspective you are selfish. Also question of quilt is inverted. Who expect guilt we as society, or the individual?
