Dina Eastwood -- 'I Still Love Clint' -- But Not His Negative Energy

Clint Eastwood's wife Dina still loves her estranged husband ... but hopes a little new age voodoo -- the use of crystals -- will rid her home of Clint's negative energy ... TMZ has learned.

Dina tweeted a pic from the Crystal Fantasy in Palm Springs ... where she dropped a couple of hundred dollars on crystals, incense, sage ... and other stuff believed to have metaphysical powers of healing and cleansing.

While in the store, Dina was overheard dumping on Clint and his new squeeze ... because they had shacked up at a home the Eastwoods own in Palm Springs.

Now Dina apparently plans to do some heavy duty house cleaning ... using the crystals and incense to remove all of the bad energy left behind by Clint's visit.
