Depression kills like anything.
It cripples one to do any thing.
It is a feeling of low self-esteem & hopelessness.
Even to go up to the grocery shop seems to be difficult for a depressed person.
The only thing a depressed person feels is to die instead of facing depression.
Depression is like darkness.
One can not conquer anything which is having a pseudo existence.
We can bring the light & darkness is not found.
Our effort should not be to conquer depression because the very effort is in a wrong direction.
  Life is full of illusions.
We have the belief that all the pleasure is dependent on others or out side conditions.
But the reality is different.
It depends on our attitude to be happy or sad, whatever the condition out side.
And the reality is that, if a person is happy, he attracts happiness.
And if a person is sad, he attracts sorrow.
The choice is ours.
  Here comes the important principle of life that we are responsible for our lives.
The reasons of depression are not outside but inside.
Therefore we can not blame anybody or any circumstances.
With taking responsibility comes the true freedom.
True freedom is what everybody wants.
But does it mean that we start blaming ourselves? No, because it is not going to help either.
It will create the guilt, which is again the cancer of the soul.
But it does mean that we will have to pass through the pain, for our acts done unconsciously in the past.
There is no escape to it.
We can start living a conscious life & depression will no more be there.
