Spiritual growth leads to long-term happiness and stability. When we blame others, we give up our own happiness. When we take responsibility, at least for what we can change, we become happier. The key thing is to catch ourselves when we are blaming others. With awareness, we automatically move towards more wholesome behaviours. Meditation can help cultivate awareness, which brings a lot of refinement in all areas of our lives. Meditate to build up awareness and also practice mindfulness of communication to move towards personal responsibility.
