A more serious guess about this artifact (actually two figurines, one on either side of a bucket handle) is that it may well have been modeled on actual Buddhist figurines from the Silk Road such as the one uncovered at Helgo, Sweden, but that such statues served a talismanic or apotropaic purpose — or were admired purely for their aesthetic qualities and exotic appeal. Swastikas of course have deep roots in Germanic tradition (as do crosses). There are, naturally, some credulous folks out there who imagine Buddhist missionaries in Viking-age Scandinavia and/or a native tradition of meditation, but so far there’s no evidence for that and I’m an Occam’s razor kinda guy.
