I ask whether she has ever attended yoga classes herself, and if her songs had ever been used as the soundtrack?
I am sitting on a plump sofa in the Dorchester hotel facing Enya, whose own sofa is quite rightly even plumper, and I tell her that, having read up on her these past few days, I have come to the conclusion that she is that rarest of things: a genuine enigma.
No matter how much one reads about the so-called Queen of New Age music – she sings in English, Latin and Gaelic, and always as if in the midst of a blissful daydream – the woman herself remains steeped in mystery.
"I wish people wouldn't think that such things were going to shock me. In fact, she's had at least three, the most recent breaking into her castle in September and tying up a member of staff.
Enya locked herself in her room and sounded a panic alarm, whereupon the stalker fled."Those kind of people have been there from day one," she says.
"I've been told I have a cross-generational appeal," she says, "and that people who used to like 'Orinoco Flow' are now playing my music to their children.
I've been very lucky." Her new album, Dark Sky Island, is her first in seven years. It's quite hard to have someone accept that – well, not that they are second to the music, but that I do need a certain amount of space for it.
Her appearance and manner is stylish and expensive, yet also old-fashioned and quietly conservative.
She exudes a sense of both reticence and control."I'm not one for walking the beaches humming a melody," explains the woman regarded by some as a queen of the New Age.
She looks younger than her 54 years, and despite the grandeur of the setting – the Dorchester is a hotel popular among the world's wealthier individuals – she must be the most unlikely music superstar in operation today. In a career now spanning four decades, Enya has very quietly shifted 75 million albums.
