From the standpoint of alchemical yoga, emotions are energy in disguise, hidden under the modes of anger, fear, sadness, excitement, etc. Transmutation is a process entirely different from suppression of emotion. Suppressed emotion requires recognition and release, and these therapeutic stages can not be bypassed. Transmutation is possible only after this initial healing already took place.
Mindfulness leads to recognition of the energy essence of emotions.
For example, anger or fear transmuted from the lower chakras into the heart chakra become compassion. We condition each other to feel a certain way by our emotions. Pranas in the people's bodies resonate with one another. By converting our negativity into positive states, we initiate others into more wholesome way of experiencing life.
