What is that "happiness" that we could encounter within, in meditation? Is it one that keeps you bubbling with joy indefinitely when you get back to your normal waking awareness? Is it an unassailable state that props you up no matter what happens to you in your normal awareness? Having said that, it is most likely that such happiness could be an infinite variety of things to people who are fortunate enough to attain it. Peace might be a more appropriate term for many people in what they attain in meditation and bring back with them to their normal awareness, Meditation is said by many masters that lived, to be an important if not an indispensable practice for people. Christ, supposedly, said that the kingdom of heaven is within. Perhaps for many people it would be an opportunity to rest the mind and one's self from the uncontrolled and ever chattering mind. It could be a means by which we could possibly have dominion over ourselves before we consider the biblical exhortation for us to have dominion over the world.
