The Hanuman Mantra
"Maarutatulyavegam Jitendriyam
Buddhimataam Varistham,
Vaataatmajam Vaanarayoothmukhyam
Sriramdootam Saranam Prapadhye"
Meaning
I surrender to Lord Hanuman whose pace is rapid like wind and quick as the mind, who is very intelligent, who has constrained his sense organs and who is the son of Vayu (Pawan), the chief of monkey tribe and the messenger of Shri Rama. His pace is as rapid as the wind and as quick as the mind.
"Om dakshina mukhaya pancha mukha hanumate karaalavadanaya naarasimhaya
