Once upon a time, there was a loving king named Dashrath who lived in Ayodhya.
He had three wives named Kaushalya, Kaikeyi and Sumitra. Despite having everything a King could hope for, he had a lingering sadness...
He pined to become a father.
King Dashrath asked a priest to come over his palace to perform a ceremony to help him heir a child. At the end of the ceremony, a divine being rose from the holy fire, holding a vessel in his hands.
King Dashrath was instructed to distribute the vessel's contents among his three wives.
He gave half of it to Kaushalya,
one fourth to Sumitra and
one eighth to Kaikeyi.
However, there still was some leftover so he gave it again to Sumitra.
The "magic potion" worked.
All three wives were expecting.
Kausalya gave birth to a son named Ram.
Kaikeyi gave birth to Bharata.
Sumitra gave birth to twins, Lakshmana and Shatrughna.
Ram Navami is the celebration of Ram's birth.
Ram is the seventh incarnation of Lord Vishnu. (Krishna is the eighth).
FUN FACT: The same magic potion that was responsible for the birth of Ram, was also responsible for the birth of Hanuman.
Vayu, the God of Wind, flew a drop of it into Hanuman's mother's mouth.
