One of the most beneficial aspects of meditation is its transformative ability to us help move through difficult emotions such as sadness, grief, anger and frustration. These are all emotions we commonly run away from feeling at first. They are scary to us. They feel like monsters that we cannot let in at any cost. Having this reaction to difficult emotions makes sense however at first - if we have a way of avoiding feeling bad, we generally take that option. However, as we know, we cannot hide from these difficult emotions forever. It feels as if the more we try to put off feeling something, the stronger it arises in us.
Meditation is one of safest and effective ways to allow difficult emotions to first arise, then be held with due respect and kindness in our body and in our mind, and lastly pass away and transform us.
