I've decided to stop using a ruler on my life. Easier said than done, I know. So I've given myself a little assistance. In the yogic tradition, we have this concept of changes happening over a very, very long time (dirgha kala; specifically, Yoga Sutra 1.14: "When that practice is done for a long time, without a break, and with sincere devotion, then the practice becomes a firmly rooted, stable and solid foundation;" "sah tu dirgha kala nairantaira satkara asevitah dridha bhumih").
So, if that works for yoga, and if yoga is life (btw, it is), then I guess I'm okay. I guess I'm not too old, too late, too dependent, too harried, too tired. I mean, I feel all of these things, for sure, but in the grand scheme of things? If I get to do this again, retaining only a little of what I've managed to learn in this incarnation? Well, I guess that would be okay.
