Kansa was killed and all good men that had fled from Mathura returned to
it. Krishna fast developed Himself as Ishvara. He restored his Guru's
son to life.
Uddhava, the embodiment of Bhakti Yoga mixed with wisdom, was the
messenger of Krishna to the Gopis. It was through him that Sri Krishna
sent words of wisdom, which He himself could not have spoken to them at
Vrindavana. For the Gopis would have spurned such words from Him, so
great was their personal love for Him. Krishna now placed another ideal
before them for meditation. They were now to seek Him, not as the lovely
Krishna, playing upon the flute, but as the all-pervading Atma to be
known by discriminating wisdom. He asked the Gopis to meditate on this
ideal, and He now returned to them as the all-pervading immutable
principle in the Universe.
In the stories of Jarasandha, Yavana and Muchukunda we find the
historical Krishna.
Jarasandha was an incongruous combination of materiality and
spirituality, (the two parts which Jiva put together). He was the
performer of Vedic Yajnas, the supporter of Brahmanas, the
representative of the old state of things. Naturally therefore he was
the most powerful king of his time and the most powerful enemy of
Krishna. Vaishnavism had to fight hard with orthodox Brahmanism.
Vaishnava kings were put to death in large numbers. Krishna could not
kill him on account of his connection with Brahmanas and with Vedic
Yajnas. He even feigned a retreat and fled away to Dvaraka. Dvaraka was
a spiritual centre on earth, created by Krishna, for the performance of
His mission as Avatara. The town was washed away as soon as Krishna
disappeared.
It will be interesting to know the future mission of Muchukunda. But the
Bhagavata is silent about it.
