One can spend a lot of money learning various forms of meditation and one can even pay to gain a diploma in meditation. Meditation has become a market product! I believe, however, that the teaching of meditation should be free. For those thinking they would like to learn about meditation I recommend Mindfulness by Tessa Watt, which is straightforward, simple and practical.
For many the practice begins with something so simple — sitting still and listening. If you are in a park or a garden, just sit still for even fifteen minutes and listen to the sounds around you and the silence within yourself. In our noise-bound society to achieve even this is something of a marvel! Then slowly begin to breathe in and out consciously: breathe in, pause; breathe out, pause. So simple.
