The Mother can help in several ways.
If you are open and receptive, full of faith and trust in Her Force can directly intervene and rectify the disorder.
In case one is not open and yet prays, Her Force may set in motion a chain of events that seem natural and yet through these the person is being led to the cure.
She can make us conscious of the inner disharmony, the root cause of the illness within us thereby making us grow in consciousness.
She can change the inner state and attitude from one conducive to the illness to another conducive for recovery.
If it is something one has to go through (for a number of reasons) She can yet support you within and help you endure and even progress inwardly through it all.
In short as many cases, as many ways.
Affectionately,
Alok Da
