Some

1. Some amongst them are like wells and pits with mouths covered by grass and creepers, while others resemble the firmament cleared of clouds and darkness. 
2. Some amongst them are of fierce dispositions (like Durvasas and others of that stamp). 
3. Some are as mild and soft in disposition as cotton (like Gautama and others). 
4. Some amongst them are very cunning (like Agastya who devoured the Asura Vatapi, and Rishis of that class). 
5. Some amongst them are devoted to the practice of penances. 
6. Some amongst them are employed in agricultural pursuits (like the preceptor of Uddalaka). 
7. Some amongst them are engaged in the keep of kine (as Upamanyu while attending his preceptor). 
8. Some amongst them live upon eleemosynary alms. Some amongst them are even thieves (like Valmiki in his early years and Viswamitra during a famine). 
9. Some amongst them are fond of fomenting quarrels and disputes (like Narada). 
10. Some, again, amongst them are actors and dancers (like Bharata). 
11. Some amongst them are competent to achieve all feats, ordinary and extraordinary (like Agastya drinking up the entire ocean, as if it were a palmful of water).
