Vyasa

“ I have never seen anyone as pure as you. O my dear brahmana, I am begging you to stay in this town."
When Sunanda heard the humble request of the headman of the town, he decided to stay for some days. That headman made every arrangement for the comfortable stay of Sunanda and engaged in his service day and night. After eight days had passed, one villager came before Sunanda, crying very loudly and said: "O pure Brahmana, last night one rakshasa ate my son." Sunanda inquired: "Where does that rakshasa stay? And how did he eat your son?" ”

“ One who attempts to save a cow from the hands of a ferocious animal, a low-class man or a wicked ruler attains Lord Vishnu.
"Wicked farmer, you saw that vulture attacking that person but still you made no attempt to save him. Now I curse you to take birth as a rakshasa."
The farmer said, "I was watching the fields for the whole night, and I am very tired, so kindly be merciful to me, o gentle sage." The yogi replied, "When someone who is daily reciting the Eleventh Chapter of Ṥrīmad Bhagavad-gītā sprinkles water on your head, then you will become free from this curse." ”

“ One who sees others in danger from thieves, snakes, fire, attack by weapons etc. -- and, even though he is capable of helping them, but does not come to help -- is punished by Yamaraja. After suffering in hell for a very long time, he takes birth as a wolf. And one who helps someone in need of help certainly pleases Lord Vishnu. ”
