How to overcome Depression with Buddhist teachings There are several scientific methods to treat the psychiatric condition depression. Is there a method to overcome depression by Lord Buddha's teachings?
Depression is not just a state of mind, it is also a chemical imbalance. 
And for various reasons (maybe genetical or other) this chemical imbalance will affect some peoples more than others. Therefore we should be careful not to respond by simply pointing logical and scholar facts and reasons that one "should not" be depressive. 

Having said that, there is some events or thoughts that will trigger the depressive mind, and I think that because meditation teach you to monitor your feelings and be able to stop being trap in a train of thoughts it might be helpful to avoid the development of depression triggering thoughts when it is still time.

On top of that there is more and more scientific studies claiming that the practice of meditation might increase your serotonin levels and immune system. There is also a good possibility that a long term practice of meditation might change you brain chemical balance and reduce your risk of depression.

So yes, I think practicing buddhist meditation (samatha-vipassana, or zazen) can be considered as a very serious asset in a therapy.
