Hanumanji has two fundamental forms, although at a subtler level he is available to us in many diverse forms. His two broad forms are Tantrika and Bhakta. The Tantrika Form is fierce and used by people with material desires, to manifest their Rajasika intentions. But Hanumanji himself does not like it when this form is summoned. He tests the sadhaka to such an extent that if the processes are not done to perfection, under a bona fide guru, the sadhaka can either become insane or lose his life. This is because Hanumanji here, is a representative of Devi, as described in the Devi Mahatmyam. The other form is the Bhakta form of Hanumanji which is desirable to attain through Bhakti and Sharanagati. In this forms Lord Hanuman is like a brother, father, even a mother and stands by the devotee, because the devotee expects nothing from Bhagawan, except His infinite love and exchanges the mood of divine love. This is the most benevolent form of Hanumanji Maharaj.
