According to the Srimad Bhagavatam (Canto 10, Chapter 8) and the Harivamsa, in a previous cosmic age, there existed eight Vasus โ celestial beings associated with the natural elements. Among them was Drona, the Vasu associated with vitality, whose devoted wife was named Dhara, meaning "the earth" or "that which sustains."
Drona and Dhara were extraordinary devotees. They lived in the celestial realms, witnessing the splendors of creation, yet they felt an unfulfilled yearning within their hearts. They did not desire wealth, power, or celestial pleasures. Their single longing was to serve the Supreme Lord in the most intimate way possible โ as His parents. They wanted to hold the Absolute Truth in their arms, to feed Him, to sing lullabies to Him, and to watch Him take His first steps. This desire was not born of ego but of the most selfless form of vatsalya-bhava (parental devotion).
Consumed by this yearning, Drona and Dhara performed intense tapasya (austerities) and meditated upon Lord Brahma, the creator of the universe. Pleased by their single-pointed devotion, Brahma appeared before them. The Harivamsa records that Drona spoke with great humility:
"Grant us this boon, O Creator โ that the Supreme Lord Himself shall be born as our son upon the earth."
Brahma, recognizing the purity of their devotion, granted this extraordinary boon. He declared that in a future age, when the Supreme Lord would descend to earth to relieve its burden of adharma (unrighteousness), Drona would be born as Nanda Maharaj and Dhara would be born as Yashoda. The Lord Himself would become their foster child, and they would experience the supreme joy of vatsalya-rasa โ the nectar of parental love for God.
The First Motherhood: Through this boon, Dhara became the designated mother of the Supreme Lord. This was the first instance of Yashoda "becoming" Krishna's mother โ through a divine decree earned by tapasya in a previous lifetime. The seed of her motherhood was planted long before she was born in Gokul.
