There are three classes of messengers; those who do not understand the orders of the master or do not care to understand, and who operate to the detriment of the work assigned them; those who do not only just as much as the order literally communicates; and those who grasp the background and significance of the orders and carry them out to the full, until the purpose is achieved. Hanuman belonged to the last and the best category. He never flinched in his efforts, whatever the obstacle, and reported back only after his conscience was satisfied with the result of his assignment. He could delve into the commands of Rama and know what His order meant. As soon as he received the order, he felt a thrust of power inside him and a new confidence that, since he had been so ordered the strength and intelligence, the audacity and the adventurous spirit needed would be granted by Rama Himself. He never had any qualms about his capacity or capability. His body and spirit were vitalised by the very fact that Rama asked him to do something. (SSS Vol. 10, p. 91)
