Revati, is daughter of the King Kakudmi and wife of the God Balarama, the elder brother of Krishna.
There’s a very interesting story behind the marriage of Balarama and Revati.
Revati was the only daughter of King Kakudmi, a powerful monarch who ruled Kusasthali, a prosperous and advanced kingdom, and who also controlled large tracts of land, including Anarta kingdom. She was born from a pile of fire; the Agnikund. Feeling that no human could prove to be good enough to marry his lovely, talented and pious daughter, Kakudmi took Revati with him to Brahmalok (abode of Brahma) to ask the God’s advice about finding a suitable husband for Revati.
When they arrived, Brahma was listening to a musical performance by the Gandharvas, so they waited patiently until the performance was finished. Then, Kakudmi bowed humbly, made his request and presented his shortlist of candidates. Brahma laughed loudly and explained that time runs differently on different planes of existence and that during the short time they had waited in Brahmaloka to see him, 27 yugas had passed on Earth and all the candidates had died long ago. Brahma added that Kakudmi was now alone as his friends, ministers, servants, wives, kinsmen, armies and treasures had now vanished from Earth and he should soon bestow his daughter to a husband as Kalyuga was near.
King Kakudmi was overcome with astonishment and alarm at this news. However, Brahma comforted him and added that god Vishnu, the Preserver, was currently on Earth in the forms of Krishna and Balarama and he recommended Balarama as a worthy husband for Revati.
Kakudmi and Revati then returned to earth, which they regarded as having left only just a short while ago. They were shocked by the changes that had taken place. Not only had the landscape and environment changed, but over the intervening 27 yugas, in the cycles of human spiritual and cultural evolution, mankind was at a lower level of development than in their own time. The Bhagavata Purana describes that they found the race of men had become “dwindled in stature, reduced in vigour, and enfeebled in intellect.” The trees and all the animals were also found in short in sizes.
Kakudmi and Revati found Balarama and proposed the marriage. Because she was from an earlier yuga, Revati was far taller and larger than her husband-to-be, but Balarama, tapped his plough(his characteristic weapon) on her head or shoulder and she shrunk to the normal height of people in Balarama’s age. The marriage was then duly celebrated.
The Rate of passing of time at Brahmalok was way slower than that of Earth. Ancient India was very well aware of this concept of variation in the rate of time lapse.! Did they imagined this phenomenon or did they really knew it.!
How could they imagine everything right.!
