meditations require a balance of effort and relaxation. In either case, too much effort makes it tiring and unsustainable, while too little effort causes you to lose your grip on your attention. The classical analogy for this balance is having just the right tension on the strings of a sitar. If the strings are too tight, they break easily, but if they are too loose, they cannot produce beautiful notes. So the strings need to be in the “Goldilocks zone” of being not too tight and not too loose.
