A devotee attaining Godhood is rare but not impossible. Lord Hanuman is a fine example of that transformation. Granted he had special abilities from birth being an incarnate of Lord Shiva but his most beautiful ability that characterises him is he unconditional devotion to Lord Rama. He himself sets a fine example of the conduct of a devotee. Numerous benefits can ensue if one invokes Anjaneya but the most eminent one is the riddance of fear and deliverance from the object of fear. itself.
