What yoga can definitely help us
Change (and, by extension, dramatically shift our experience of life) is the texture of our own mind, the stickiness of certain emotions and views, and above all, the quality of our inner state. The most powerful shifts occur when we experience a change in the way we identify ourselves—when we can see ourselves as the Self, the unchanging consciousness behind the mind, or when we can identify ourselves as the witness to our thoughts rather than becoming our thoughts and feelings.
Arguably, the core of our yoga practice is the work that we do to purify, reforge, and replace the inner patterns that in Sanskrit are called samskaras. Samskaras are the accumulated impressions—in scientific terms, the neuronal patterns—that create our character, our ways of thinking and acting, and our perspective on life.
The word samskara can be translated just the way it sounds in English: “some scars.” Samskaras are energy patterns in our consciousness. I always picture them as mental grooves, like the rivulets in the sand that let the water run in certain patterns. Samskaras create our mental, emotional, and physical default settings.
