WITHOUT ATTACHMENT TO THE OUTCOME
This is the idea that we can practice experiencing each moment, not missing a thing, not missing the pretty colors, people and blessings right in front of us. On the mat we use the body to observe where we are, making sensitive adjustments to stay tuned in, and then allow the unfolding. This keeps us mindful to the moment rather than the goal or outcome. The Yoga Sutras speak to this as vairagya (non attachment), chapter 1 verse 15.
Key things to know include:
Non-attachment is not suppression: Non-attachment is not a mere personality trait that one practices in dealing with the other people of the world. It is very easy to fool oneself into thinking that non-attachment is being practiced when what is really happening is pretending to be non-attached. It is like saying that you have lost your inner craving to some object while inside you are longing for it intensely. Non-attachment is not a process of suppression or repression of wants, wishes, desires, thoughts, or emotions. It comes by the ongoing practice of awareness of the existence of attachments (kleshas, 1.5, 2.3) and gradually letting these weaken (2.4).
Non-attachment is cessation: If attachment does occur (whether attraction or aversion), wherein attention wraps itself around a deep mental impression, the ensuing non-attachment comes from the cessation of mental clinging, not from an act of prying attention away forcefully. It is easy to hear of the philosophy of non-attachment and then mistakenly walk around lying to ourselves, internally saying something like, "I'm not attached; I'm not attached." This is not non-attachment. It is better to see realistically where our minds are attached, and then learn to systematically release that coloring through the external and internal practices of yoga meditation.
Non-attachment is not detachment: It is not mere semantics to say that non-attachment is different from detachment. Detachment implies that there is first attachment, and that you then apply some method or technique to disconnect that attachment. It implies an act of doing something to cause the separation to occur. Non-attachment, on the other hand, means that the connection simply does not occur in the first place. Non-attachment is not a case of doing something, but is instead a non-doing sort of thing. It means that your attention does not grab onto that impression in the mind in the first place.
Non-attachment deepens through all levels: Patanjali explains that non-attachment applies to progressively deeper levels of our being. While we might begin with our more surface level attachments, such as the objects and people of daily life, the practice deepens to include all of the objects or experiences we might have only heard about, including the many powers or experiences of the psychic or subtle realm. We gradually see that even these are nothing but distractions on the journey to Self-realization, and we learn to set them aside as well.
