O best among monkeys, in the execution of this mission you are the decisive authority. O Hanumān, take up the effort with resolve and become the remover of my sorrow; for the one who reflects and strives, that very effort becomes the means of ending grief.
"If I have managed to come here, why not the other powerful ones? The superior leaders are not sent (as messengers). Only ordinary ones like me are.
Dharma here is steadfast responsibility: one should undertake a righteous task with thoughtful effort, because sincere striving itself becomes the means to remove suffering.
In Laṅkā, Sītā speaks to Hanumān, urging him to take initiative and successfully carry out the mission of contacting Rāma and enabling her rescue.
Hanumān’s virtue of purposeful effort (utsāha) guided by discernment—acting decisively, not passively, in service of a righteous cause.
