I’ve written from time to time about the benefits of meditation, and also contrarily about the uselessness of meditation. Against the view that ‘meditation delivers benefits X and Y’ is the view that ‘meditation is simply the experience of life, being in the moment’. The latter does not mean stopping to think, “this meditation will put me in the moment,” but just sitting and being open to whatever the moment (life) happens to be. The latter is true zen.
Here is a beautiful zen story that illustrates the mysterious adventure of ‘just sitting’ without any ideas of gaining or losing.
