Unfortunately, many claim that mindfulness leads to happiness. This breaks with the whole concept of looking at it without judgment. Mindfulness practiced properly does not lead to happiness; it leads to a greater awareness of whatever you are experiencing. If you are mindful of your depression, for instance, you will experience depression more clearly and more intensely.
Mindfulness and the yoga techniques it was based on were developed as a way to experience bliss. It is a complete misunderstanding of what bliss means that the result of mindfulness is called happiness. Happiness is the opposite of sadness. It is part of the duality of delusion that makes us judge one thing better than another. Such judgment is the opposite of mindfulness; it is wanting things to change instead of accepting them as they are
Every moment of our lives is an opportunity to be in bliss, but we avoid those with the most potential because we think that the difficult experiences need to be removed first. We are closer to experiencing bliss during the difficult times because they challenge us to break from our attachment to happiness. As bliss is beyond the duality of happy-sad, gain-loss, pleasure-displeasure, and even health-illness; we cannot truly know bliss until we see it in our pain. Once we find bliss in pain, we find it everywhere. Mindfulness can help you to find it.
