Ego is often the source of unhappiness. Misguided perceptions often lead to unnecessary suffering. The words that led to your anger or fear may have had a completely different meaning and intention. Many times the suggested consumption can be harmful to your body and mind. Many toxins are ingested through unmindful consumption of violence, hatred, and vice shown on TV, in movies, music, books and magazines.
Mindful consumption is a component of our path to happiness.
Unfortunately, our unwholesome attitudes, the seeds of our unhappiness lie at the depths of our consciousness. It is not easy to change them. Psychotherapists try to find the cause of suffering and try to show the person how they can treat the cause of the suffering. One of the great teachings of the Buddha 2500 years ago is that suffering exists, that there is a cause of suffering, that suffering can be eliminated and there is a path to end suffering. The first steps on the path are contained in the Five Mindfulness Trainings as taught by Thich Nhat Hanh.
