[meotimdihia]

Because meditation methods are all derived from Buddhism. If we don't understand basically then we don't know the real reasons and we don't have enough motivation for why we need to meditate.

And our mind has to be in a peaceful state to have the best in mediation.

For example about this: gamers always say they play worse when they are old. In reality, it is almost like their mind has many problems with worrying about family or money, not like when they are young.

And we can't have peace of mind if we are just meditating. We need to understand the Noble Eightfold Path. https://i.imgur.com/Sv9Sdoj.png.

Meditation is a necessary but not sufficient condition.
