Uttanka

Muni, named Uttanka, being much troubled by Taksaka, thought who could help him in his taking revenge on Taksak and, seeing the king Parîksit's son the king Janamejaya a proper person came to Hastinâ to the king and spoke out thus :-- “O good king! 

1. Thou dost not know when to do a thing that ought to be done; 
2. Thou art doing at present what ought not to be done; and 
3. thou art not doing what should be done now.
