Elements is probably one of the best places (along with Tubular Bells, of course) to start with Mike Oldfield. This has a great selection of his music over the years up to his Tubular Bells 2 album. You get a fair range of his instrumental stuff, as well as his other songs such as the excellent 'Family Man' which has one of the best Oldfield solos ever, in my opinion. He has always been an original, enigmatic character and this collection goes some way to introducing you to the music of this unique songwriter and musician. Well worth a try.
