it helps you disociate an emotions from thoughts... worked for me
they have a nice little video lesson at
http://www.buddhanet.net and some lessons in their Buddhanet Audio section..lower left on home age... meditation is simply traing the mind.. depression and other problems can just be symptoms of and untrained mind.. it isnt 'working' for 'you'... you own it, learn to make it do what it is supposed to do.. work for you.. it is its own worst maste.. the Buddhists call an untrained mind..."the Monkey Mind".. always here and there getting nothing done... the mind with roveing thoughts like slowly turning the tuner on an AM radio.. is the conventional mind. the nature mind that lies quietly underneith is luminous, calm and blissful
