And among the foremost apsarases and within the bodies of gandharva-women, take on the form of monkeys and beget sons of equal prowess.
Incarnate as monkeys in the womb of chiefs of apsarasas and gandharvas. Create sons who have the knowledge of deceitful tricks, who are brave, who match wind in speed, who are endowed with intellect and statecraft, who are determined, who are knowledgeable in various means of achieving victory, who are supernatural bodies, who possess capability of employing and resisting weapons, who resemble those who subsist on amrita (immortals) and are equal (to Visnu) in prowess.
Dharma is shown as cooperative responsibility: celestial powers align their abilities and even assume new forms to support the restoration of moral order on earth.
Brahmā specifies the means of generating the vānara allies—through procreation involving chief apsarases and gandharva-women, with the gods manifesting in monkey-form.
Service to a righteous cause through self-adaptation—willingness to assume appropriate roles/forms for the sake of dharma.
