Well, yes and no. Meditation does produce lovely blissful feelings sometimes. But they are not the purpose, and they don’t always occur. Furthermore, if you do meditation with that purpose in mind, they are less likely to occur than if you just meditate for the actual purpose of meditation, which is increased awareness. Bliss results from relaxation, and relaxation results from release of tension. Seeking bliss from meditation introduces tension into the process, which blows the whole chain of events. It is a Catch-22: you can only experience bliss if you don’t chase after it. Euphoria is not the purpose of meditation. It will often arise, but should be regarded as a byproduct. Still, it is a very pleasant side effect, and it becomes more and more frequent the longer you meditate. You won’t hear any disagreement about this from advanced practitioners.
