During the solar eclipse, all the Vrajavāsīs went to meet with
Kṛṣṇa at Kurukṣetra; and all the kings, Pāṇḍavas, and queens of
Dvārakā also came. The queens of Dvārakā brought a large quantity
of gold to donate in charity, and as they were getting ready to
make the donation, Nārada came to receive it.
The queens wanted to donate Kṛṣṇa’s weight in gold, and Nārada
was very happy to hear this. But Kṛṣṇa is Svayam Bhagavān, the
original Supreme Personality of Godhead. How can He be measured
by gold? It is not at all possible.
In order to determine how much gold to give Nārada, the queens
decided to use a scale, with all the gold on one side and Kṛṣṇa on the
other. However, no matter how much gold the queens placed on the
scale, Kṛṣṇa was heavier than the gold. The queens then took all of their
ornaments and placed them on the scale; but still Kṛṣṇa was
heavier.
Finally Nārada said, “I am taking Kṛṣṇa from here, because you
could not produce enough gold to equal His weight. I will make Him
my disciple.”
Kṛṣṇa became ready to leave, at which time all the Queens began
looking at each other, wondering what to do. They decided it would
be best to go to Srīmatī Rādhikā. They approached Rādhikā and told
Her of their dilemma. Rādhikā then came to the palace, took one
tulasī leaf and washed it with Her tears, and chanted Kṛṣṇa’s name.
She then removed all the gold from the scale and placed on it the
tulasī leaf, which immediately outweighed Kṛṣṇa. The side of the
scale with the tulasī leaf went down, and Kṛṣṇa went up.
It was Nārada Ṛṣi’s desire to show everyone present that the
combination of all the queens of Dvārakā was not equal to one
Rādhikā; and all of their gold was not equal to the value of one of
Rādhikā’s teardrops.
