Aparigraha, according to several yoga traditions is the act of non-possessiveness. According to Rolf Gates, author of "Meditations from the Mat", it is the art of appreciating emptiness in one's life and before we can learn to appreciate that emptiness, we must first learn to let go.
I had used this quote in a post I did nearly two years ago (my, how time flies!). The past two years has given me time to assimilate this thought and reflect on its meaning; like having a deeper perspective.
It is within our nature to not think of our thoughts as being a part of the physical world, or a part of our inventory of possessions. Hoarding is a behavior that we all possess too, and it is in the hoarding of so many thoughts and emotions that interfere with experiencing aparigraha. It requires quieting the mind, emptying it and letting go of expectations. This is hard for us to do because we are wired to react and respond to what is around us at all times. It is a part of our survival mechanism for this physical world. But, in order to transcend to the metaphysical, you do need to empty that 'pot'; surrender to whatever it is to come and trust it. This state of surrender, when achieved is truly blissful because it is without all the distractions of the inner chatter of our minds.
I can't say that I have ever achieved this absolute state of bliss, but I can say that I have experienced various levels of it.
For example, this past Friday, there were several art receptions of some friends of mine (Robert Redus and Barbara Shapiro) taking place in different galleries. I wasn't sure if I could make either of them since I was also expecting out of town company. As it was, my company hadn't arrived yet, and so I did have the chance to attend the receptions. At the first location, I ran into my dear friend, Leau. She had a similar game plan as I did, so we ended up traveling together for the evening. It was so serendipitous! We hadn't seen each other in quite some time and meeting up in this manner and spending the evening together couldn't have happened if we had tried to plan it. For myself, I had let go of having any expectations first about being able to go, and second trying to meet up with anyone to go with me. I was content to let the evening unfold without any orchestration on my part. It ended up being the perfect evening! I truly believe that in that letting go of expectations, it allowed for something even better to happen.
Granted, this is not really a metaphysical example of surrender and letting go of expectations, but it is indeed valid. This is the kind of thing that I call the starting points, or the germination of the process. In this case the process of learning what aparigraha is. It is a more practical, day to day experience of what it can be. It is in the simple exercises like this that can assist in leading you to higher levels of the process.
So, if you find yourself stressing out about something, stop and think about letting go of those thoughts and more importantly, expectations. Surrender to whatever it is that will present itself. I find that when I do so, I am always pleasantly surprised.
