Samadhi is the matter of Buddhist monks only

Though I never saw monk in Samadhi practice while I was living in the pagoda, I believe that Samadhi must be one of the duty of the monk. In many places in Cambodia, there were and are monks who are good in fortune telling, efficient in removing bad luck through showering water to people or other praying. This kind of magical power was generally known as the result of Samadhi.

With this kind of insight, I considered Samadhi as the duty of the Buddhist monks only because the monks are the ones who maintain the Buddhism. So Samadhi is not the job of the householders except the old people who renounce the household and go to live in the pagoda.
