A yoga practice often involves a lifetime of learning. The safe and nurturing beginnngs often sprout to new ventures.
Many start with a basic learning class but we want more. Hustling to "get" the breathing pattern. Honestly sensing the placement of each pose only to crave the next, deeper sensation.
Again, safe and nurturing as the little we bring home acquires an ongoing craving for the sanctuary of a forward bend.
Since we know we can achieve more, the myriad of classes and forms start to attract us. This never really stops. With so many options and opinions. Get it hot, get it slow, like water or earth, yin or yang.
Stay with any form long enough and the introverted nature of yoga comes into focus. You begin to sense the center -- our center. The world start to quiet itself.
When you move from one to the next the phases in yoga start showing you a spiral. A repeated evolution. Get what you can from each arch of the path let it flow inward.
