I certainly agree. The first Buddhist meditation instruction I received used this technique, and that is what I primarily practise.
However, any technique needs time to understand and get used to, and if one wants to evaluate an approach, I would recommend following the instructions from one
reputable teacher (be it Mahasi, Buddhahdasa, Brahm, or whoever) for some time (months). As far as I have observed, flitting between approaches, tends to lead to confusion and dissatisfaction.
