Lord Hanuman symbolically stands for pure devotion, complete surrender and absence of ego or the lower self. As the son of Vayu, symbolically he also stands for the subtle body consisting of the breath body, the mental body and the intelligence body. Here we explain Hanuman as the mental body in a human being.
The mind is fickle (like a monkey) and jumps from place to place, going after things, engaging itself in innumerable activities that disturb the peace of the place. The mind, like Hanuman can also travel where it wants to. It can fly in the air, cross the continents and the worlds in an instant with the speed of thought and reach any one and anything it wants to mentally.
It can also expand or contracts itself at will (again like Hanuman). So long as it remains under the control of pure animal passions and the activities of the sense, it remains unstable and mischievous, causing a lot of the disturbance in the world of the individual.
But once it surrenders to the inner self and becomes devoted to it completely and unconditionally, it assumes miraculous powers and performs stupendous feats like Hanuman, working for the divine cause helping the lower self (Sita) and the Soul (Rama) to come together and become united.
By killing all the evil thoughts with its determination, it also lays a firm foundation for the kingdom of God (Ramarajya) to become established in the body. Hanuman is thus symbolically the mind principle ever absorbed in the contemplation of God and totally surrendered to Him.
But this is not the only interpretation available for Hanuman. As “Hanuman”, he is the one without any doubt (anuman) as to the existence of Rama (God). As anjaniputra, he is the one who comes accidentally into this world, but by his efforts ascends to the greater heights of spiritual evolution.
As Vayuputra he is the breath body in us and can help the lower self (Sita) that is lost to ignorance to reunite with its true companion, the inner soul (Rama). As Veeranjaneya, he is the source of courage and confidence for many a timid heart.
As Bhajarangbali, he is strong in both devotion and physical strength. He is an ocean of virtues and friend of the pure hearted. He loves the ascetic qualities in man because only those who are detached and mentally free from the luxuries of life and desires of their bodies can truly concentrate on the divine and attain Him.
Hanuman is regarded as the Superman, the perfect man, the knowledge body (gnana guna sagara) in man, the immortal man (chiranjeevi) and also the animal man (va+nara).
