I do not think it needs to be a duty or as a means to a material end. Some people think they are holier than thou if they meditate. Especially if they torture themselves for hours in postures that are uncomfortable and painful. This is like crawling to Lourdes on your knees. It becomes a form of penance.
If it is not a delightful process, there is no point in it. It will not help you win the lottery or appease God or do anything that produces a material result. It is all about getting in touch with your spiritual self because it feels great!
