As human living and incarnated beings, we all have samskaras, habitual patterns of thoughts, actions and words, innate or acquired, which may have been useful at some point for our survival but which may not be beneficial anymore to us today.
They may be physical (a way of acting on a daily basis), emotional (a way of reacting to life events), psychological (a tendency to anxiety, depression), immune (tendency to reject what is foreign, to let everything in). They affect all aspects of our being.
Some are positive, constructive (knowing how to listen fully, taking action from the center, knowing how to set limits) others much less.
With the practice of yoga, we learn to identify them, to rub them along, to tame them in order to gradually evolve and integrate them within our whole being: physically (what is our attitude on the mat? does it strengthen the pattern ?), emotionally (how does this emotion manifest within me ? can I see it arising, before it has submerged me?).
Do you have a minute, now, to reflect on one of your samskaras that you would like to make evolved?
