Raikva Says,

Raikva is depicted as a recluse, dirty, a clumsy fellow living under an old bullock cart and hence he earned the name Raikva the cart-man. Raikva was a great attained soul and even the birds that fly in the sky knew him! What he instructs to King Janshruti is an ey-opener.

   Once the swans werer flying over the palace of King Janashruti. King Janashruti was sitting on the terrace watching the sky. There were golden plates full of eatables around him. The swan leading the formation of the birds warned the other birds not to look at the golden plates and the contents and passed the remark that the King, although a knowledgeable person is not anyway wiser than that cart-man Raikva.

  King Janashruti who knew the language of the birds bewildered and sent for the cart-man Raikva. The attenders looked for this fellow everywhere and returned and reported the matter. He sent his ministers and finally they found him. They requested him to come to palace on the orders of the King. Raikva said that he knows no king and he is not obliged to anybody. Finally the king himself came with  500 hundred cows with a gold coin tied to each of its horn and requested him. When this did not get any response he brought his daughter wearing lots of ornaments and offered her in marriage and requested him to accompany to palace. Finally, reluctantly Raikva came to the palace and he was given a bath with fragrance and good clothes to wear. 

  The king narrated what he heard from the swans and requested him to impart him the knowledge. Raikva, in reply, asked him "Who is the king and how he got the throne?". King Janashruti proudly said that he is the king and got the throne from his father, who in turn got it waging a war with the neighboring country. "Oh! Then this throne is not yours, you shudra, rebuked Raikva". Then he asked the king:"Who would be the next who would sit on this throne that originally belonged to somebody else?"

  King got the worst shock of his life when he realized the fact that anybody, may be the minister's son, the army chief, or the king of the neighboring country, could get the throne since he had no issues. Thus, he realized the truth, gave up everything and went to vanaprastha ashram to meditate on the 'Truth'. Bt the way, Meditation is nothing but "med i tat i(eye) on!" (med, meaning, medicine for cure of all mental afflictions).
