Karmic repercussions of castrating animals:
仁欽多吉仁波切曾經幫助一位得肝癌的醫生，肚子脹得非常大，身為醫生的他，卻對自己的病束手無策，因而來求 仁欽多吉仁波切幫助。仁欽多吉仁波切看到他這個病的因果，是因為他曾經閹了很多的動物。但是這位醫生本身並不是獸醫，怎麼會閹這麼多動物呢？原來是以前他曾在海南島當軍醫，閒著無聊，就把當地的雞、狗等動物抓來閹掉。就像有人覺得自己在救流浪貓狗，認為不要再讓這些貓狗們繁殖下去，或是把自己養的寵物抓去閹了，這樣很不好的，都會有果報。設想如果你們沒有生病，好端端地，會願意讓人家隨隨便便抓去閹掉嗎？既然自己不願意被閹，就不要做這種事。
Rinchen Dorjee Rinpoche once helped a doctor suffering
from liver cancer. This man's stomach was very distended and though
a doctor himself, he was helpless about his own sickness, therefore
came to seek Rinchen Dorjee Rinpoche's help. Rinchen Dorjee
Rinpoche examined the karmic causes of his sickness and found that
this man had castrated many animals in the past. But this doctor
was not a vet, so how would he have castrated so many animals? It
turned out that when this doctor was in Hainan Island as a military
doctor, while he was free and feeling bored, decided to castrate
the local chickens, dogs etc. and other animals. He felt that he
was doing a good deed to the loitering cats and dogs and felt that
it would be good not to let them continue to multiply. Even
bringing one's own pet to be castrated, it is not good and there
will be negative karmic results. Just think, if you were to be
healthy and fine, would you be willing to have someone castrating
you casually? If you are not willing to be castrated, then don't do
such things.
