Let me share with you what my learned friend told me of one riwayat. It is a dialogue between Allah and The Nafs. The conversation was in Arabic but I think all of us will understand:-
Allah: Man Anta?
For Nafs's arrogance,it was sent to Hell for afew years.
Then, Allah called The Nafs and asked it the same question.Allah got the same answer.
Then, Allah sent The Nafs to the Hell of Ju'(Hunger) for a few years.
When Allah summoned The Nafs back to answer the same question,here is The nafs reply:
Anta Rabbi.Waana abbduka.
That is THE POWER OF HUNGER over our nafs.
