Does he mean some kind of non-mystical mystical experience as vehicle for being happy?..
Here is another Harris quote to give you an idea of what he means…
"… let me describe the general phenomenon I’m referring to. Here’s what happens: a person, in whatever culture he finds himself, begins to notice that life is difficult. He observes that even in the best of times—no one close to him has died, he’s healthy, there are no hostile armies massing in the distance, the fridge is stocked with beer, the weather is just so—even when things are as good as they can be, he notices that at the level of his moment to moment experience, at the level of his attention, he is perpetually on the move, seeking happiness and finding only temporary relief from his search.
…
In this context, certain people have traditionally wondered whether a deeper form of well-being exists. Is there, in other words, a form of happiness that is not contingent upon our merely reiterating our pleasures and successes and avoiding our pains. Is there a form of happiness that is not dependent upon having one’s favorite food always available to be placed on one’s tongue or having all one’s friends and loved ones within arm’s reach…? Is it possible to be utterly happy before anything happens, before one’s desires get gratified, in spite of life’s inevitable difficulties, in the very midst of physical pain, old age, disease, and death?

…certain people, for whatever reason, are led to suspect that there is more to human experience than this. In fact, many of them are led to suspect this by religion—by the claims of people like the Buddha or Jesus or some other celebrated religious figures. And such a person may begin to practice various disciplines of attention—often called “meditation” or “contemplation”—as a means of examining his moment to moment experience closely enough to see if a deeper basis of well-being is there to be found.
Such a person might even hole himself up in a cave, or in a monastery, for months or years at a time to facilitate this process. Why would somebody do this? Well, it amounts to a very simple experiment. Here’s the logic of it: if there is a form of psychological well-being that isn’t contingent upon merely repeating one’s pleasures, then this happiness should be available even when all the obvious sources of pleasure and satisfaction have been removed. If it exists at all, this happiness should be available to a person who has renounced all her material possessions, and declined to marry her high school sweetheart, and gone off to a cave or to some other spot that would seem profoundly uncongenial to the satisfaction of ordinary desires and aspirations.
One clue as to how daunting most people would find such a project is the fact that solitary confinement—which is essentially what we are talking about—is considered a punishment even inside a prison. Even when cooped up with homicidal maniacs and rapists, most people still prefer the company of others to spending any significant amount of time alone in a box.
And yet, for thousands of years, contemplatives have claimed to find extraordinary depths of psychological well-being while spending vast stretches of time in total isolation. It seems to me that, as rational people, whether we call ourselves “atheists” or not, we have a choice to make in how we view this whole enterprise. Either the contemplative literature is a mere catalogue of religious delusion, deliberate fraud, and psychopathology, or people have been having interesting and even normative experiences under the name of “spirituality” and “mysticism” for millennia.
Now let me just assert, on the basis of my own study and experience, that there is no question in my mind that people have improved their emotional lives, and their self-understanding, and their ethical intuitions, and have even had important insights about the nature of subjectivity itself through a variety of traditional practices like meditation.

Most us think that if a person is walking down the street talking to himself—that is, not able to censor himself in front of other people—he’s probably mentally ill. But if we talk to ourselves all day long silently—thinking, thinking, thinking, rehearsing prior conversations, thinking about what we said, what we didn’t say, what we should have said, jabbering on to ourselves about what we hope is going to happen, what just happened, what almost happened, what should have happened, what may yet happen—but we just know enough to just keep this conversation private, this is perfectly normal. This is perfectly compatible with sanity. Well, this is not what the experience of millions of contemplatives suggests.

From the point of view of our contemplative traditions…our habitual identification with discursive thought, our failure moment to moment to recognize thoughts as thoughts, is a primary source of human suffering. And when a person breaks this spell, an extraordinary kind of relief is available.
…
One problem with atheism as a category of thought, is that it seems more or less synonymous with not being interested in what someone like the Buddha or Jesus may have actually experienced.
…these experiences have a lot to say about the plasticity of the human mind and about the possibilities of human happiness.
…millions of people have had these experiences, and many millions more have had glimmers of them, and we, as atheists, ignore such phenomena, almost in principle, because of their religious associations—and yet these experiences often constitute the most important and transformative moments in a person’s life."
