The beloved salutation to Hanuman — swift as thought, fast as the wind, master of the senses, foremost among the wise — taking refuge in the messenger of Shri Rama.
As the dhyana (invocation) before Hanuman Chalisa, Sundara Kanda or Hanuman puja — and by travellers and students any time strength, focus or fearlessness is needed.
