Listen, as a sacred narrative unfolds, revealing the secret practice of the twelve-syllabled mantra dedicated to Hanuman, the mighty son of the wind. This mantra, renowned for its power, marks the culmination of armor and weapons, and bestows the eight great siddhis upon the practitioner. Hanuman himself is the deity invoked, with the first syllable as the seed of the mantra, and its energy expressed through the potent utterance 'hum'. The imagery evoked is one of immense strength: Hanuman, uprooting a great mountain and charging towards Ravana, blazes like fire, his radiance rivaling ten million suns. His cry resounds through the battlefield, “Stop, stop in battle, O wicked one!”—a terrible, awe-inspiring sound. To honor this power, one should offer one-tenth of rice mixed with milk and ghee, a humble yet potent tribute. Conceiving Hanuman’s form through the root mantra, the devotee prepares for worship, and now, the practice is revealed for the welfare of all worlds. This secret, supreme and swift in its accomplishment, is hidden even from the gods. At dawn, after bathing at the riverbank and seated upon kusa grass, the practitioner begins. Eight handfuls of flowers are offered, as one meditates upon Rama and Sita. Using a stick smeared with sandalwood, the form is drawn. With the root mantra in mind, meditation deepens, and offerings commence, beginning with water for Hanuman’s feet. The six limbs are worshipped upon the filaments and petals, as are Jāmbavanta, Kumuda, and the lord of the filaments. When the mantra is perfected, the minister achieves his desired aim inwardly. The best among practitioners must first take possession of the ground, binding the directions through nyāsa and meditation. When a hundred thousand recitations are reached in a single day, a great worship is performed, continuing day and night until the vision of Hanuman arises. Then, pleased, Hanuman appears before the foremost devotee, who may then receive a boon and enjoy happiness. This secret, so difficult to obtain that even the gods covet it, has now been revealed. Afterwards, one meditates on Hanuman, the son of the wind, with the sky and moon as his backdrop, and as previously described, honors the sages and the six limbs. In the vision, Ravana is seen rushing forth to conquer, and the practitioner, channeling anger towards the guru, seizes the great mountain. The proclamation echoes throughout the universe as Hanuman assumes a terrible, awe-inspiring form. Worship follows the prescribed rules of the mantra, and the secret practice continues. Rising at Brahma-muhurta, pure in body and having completed daily duties, one recites the root mantra and sprinkles offerings equal to the count of the sun. Whether on mountain or in forest, the ritual of taking possession of the ground is performed first. Breath is regulated and exhaled according to the method described, and meditation is carried out as before, worshipping the lord of the monkeys. On the seventh day, a great act of worship is performed. Having offered great fear, only a third remains, and Hanuman grants the desired boon to the practitioner. The boon is attained immediately—truly, there is no doubt. For urgent requests, one invokes the pair of winds, calling out “Hanuman.” Thus, the sacred practice is complete, and Hanuman’s blessings are bestowed upon the faithful practitioner.
