According to mother
In human life the cause of all difficulties, all discords, all moral sufferings, is the presence in everyone of the ego with its desires, its likes and dislikes. Even in a disinterested work which consists in helping others, until one has learned to overcome the ego and its demands, until one can force it to keep calm and quiet in one corner, the ego reacts to everything that displeases it, starts an inner storm that rises to the surface and spoils all the work.
This work of overcoming the ego is long, slow and difficult; it demands constant alertness and sustained effort. This effort is easier for some and more difficult for others.
So what is Ego ? Not knowing yourself as the divine atman and thinking of yourself as the body or husband, father, mother, doctors, teacher, worker etc
And that is the tragedy from which difficulties are a friendly reminder – a wake up call
This is only by experience – not a mental projection which you create in your mind by reading I am atman , I am soul, I am brahman, I am shiv
What does it feel like to experience? Go ask someone who is there
