What you describe when you refer to the walk in the forest is being keenly aware (or dare I say, awakened to) all our senses simultaneously. I wouldn’t call this multitasking. In fact, we have lost our ability to be aware of our various senses simultaneously because of multitasking!
The baby being nursed while the mother does something else is also not a fair example of multitasking because the baby is doing its thing and the mom is doing her thing! â˜ºï¸
If the mind were to be likened to a stream of flowing water, multitasking is like using a spoon to fill up a bucket! It is inefficient and energy depleting. My practice in taijiquanteaches me everyday how important (not to mention tough) it is to move the body slowly. When I say “tough” I mean that we are so used to moving fast that slowing down is an effort but once the body is trained in slow movements, you experience an efficiency in use of muscles. Needless to say, the body becomes stronger. This is my experience with slowing down.
