Mañjuśrī, Monju, Wenshu - are all the same Avatar.
No matter what name is used, the key Ideology to remember is - Wisdom.
Mañjuśrī is the Bodhi-sattva of Wisdom. His flaming sword represents the Discernment that is needed in order to perform Wisdom. Since the process of Wisdom is a moving phenomenon, the sword/[the mind+body] acts as a tool to cut through the Illusions of reality, and into the third reality; the formless form of the Unconditioned State.
If an Individual escapes into the third reality, while also using the Knowledge of Truth, the individual will have a greater Wisdom needed for a particular situation.
Mañjuśrī represents this understanding of Wisdom.
