Now here's my philosophical question, how can you fail in yoga?
No really, you can't. You can't fail in yoga unless you designate some crazy, unattainable expectation for yourself. Yoga can meet you where you're at, not just where you want to be. And that's why yoga is such a beautiful thing that we need to embrace for its flexibility (no pun intended) and not focus on some sort scale for standards of achievement. Just let it be.
Should you not continue to work and grow in your practice? No, you absolutely should if that's what you want to do. But if you don't have the health, energy, or ability to further challenge yourself to achieve more difficult or deeper postures, work on "being" with that. Hold that space in your life for a practice without expectation of results, because once you can do that, it helps to take away that fear of failing. I'm always working on that. Especially after this whole experience with Aplastic Anemia.
I know my stamina and strength are not what they used to be, I mean, I get winded by too many stairs or too tough a yoga practice. Yet I'm okay running/jogging on a flat surface and am able to slowly build up my time length. What gives? Accepting and not feeling defeated by where I'm currently at.
Is this failure? Certainly not. Nor is it a failure to not be working at a job right now. While I'm not always confident in or feel a bit disconnected from a purpose at this time, I know deep down (and keep reminding myself) that I am working on healing, getting better again so that I can continue to live a full and healthy life, free from major backslides into neutropenia and the need for transfusions.
So stop labeling things as either a "success" or a "failure" because from where I stand, there seems to be a lot of gray areas. And, I think (finally), that I'm completely okay with that.
