Now, let us see some verses from Valmiki Ramayana.
2-70-5 (BOOK 2, BOOK OF AYODHYA, AYOODHYA KAAND`A), CHAPTER 70, VERSE 5.
Atra vims`ati kot`yaha tu nripateer maatulasya tee
Dasha koot`yaha tu sampuurn`aaha tathaiva ca nripa aatmaja.
"Oh Prince! Of these valuable gifts, 100 crore (a billion) are for the king (Keekaya) and 10 crore (100 million) are for the maternal uncle (of Bharata).
The billion and the 100 billion are mind boggling. There may be hyperbole. Or the Royal Priest might have wanted to have good relations with the Keekaya King. But how much the Keekaya King is giving as gifts through his nephew? : Just 2,000 gold coins.
2-70-20 (BOOK 2, BOOK OF AYODHYA, AYOODHYA KAAND`A), CHAPTER 70, VERSE 20.
Rukma Nishka sahasree dvee shod`as`a as`va s`ataani ca
Satkritya Kaikeyii putram Keekayoo dhanam aadis`at.
The Keekaya King ordered gifts of 2,000 gold coins and 1,600 horses to the sons of Kaikeeyi.
Why did the Keekaya king gift horses in such large quantities? We can deduce that he was expecting that there would be a battle for succession in Ayodhya between Bharata and Rama in future.
