It strikes me that it is very fortunate that meditation can be pleasurable. If there was no fairly immediate rewards then surely hardly anyone would make any kind of progress towards enlightenment. It almost like it is designed to have little pleasant staging posts where the practitioner can rest before continuing onward with the journey.
But why is meditation pleasurable? Could it be insightful but barren or is there something inherent in the practice that is pleasant and the pleasant quality of meditation is a necessary quality? What do the texts say about the pleasant qualities of meditation? Is there any accounts about why it is pleasant perhaps mythic accounts or explanations?
