Take it to your gentle edge of expression – where any more would be too much, and any less would be too little.
These words also bring to mind Lev Vygotsky and his idea of ZPD – the zone of proximal development. Vygotsky believed that children could learn from watching and following adults, with the adult assisting the child to go beyond what the child was able to do on her or his own. He felt that optimal learning experiences should take place in each child's ZPD, with that zone being specific to each learner.
Candy Anderson, a learning specialist with whom I've had the pleasure of being colleagues and friends for upwards of 10 years, noted that "as Vygotsky would say, we need to start where the learner is and then move forward." She clarified that "the zone really applies to an individual's range of knowledge."
I have learned yoga through a combination of observing my teachers, following their cues, giving my teachers permission to make subtle changes in my postures as they adjust my body into a pose, and practicing regularly. My teachers have taken me beyond what I could do on my own. They have helped me to get to my gentle edge of expression and over time, with their assistance, the placement of that gentle edge has shifted. They have met me in my ZPD and guided me beyond.
