Then, O ye friends of God! Ye must not only have kind and merciful feelings for mankind, but ye should also exercise the utmost kindness towards every living creature. The physical sensibilities and instincts are common to animal and man. Man is, however, negligent of this reality and imagines that sensibility is peculiar to mankind, therefore he practices cruelty to the animal. In reality what difference is there in physical sensations! Sensibility is the same whether you harm man or animal: there is no difference. Nay, rather, cruelty to the animal is more painful because man has a tongue and he sighs, complains and groans when he receives an injury and complains to the government and the government protects him from cruelty; but the poor animal cannot speak, it can neither show its suffering nor is it able to appeal to the government. If it is harmed a thousand times by man it is not able to defend itself in words nor can it seek justice or retaliate. Therefore one must be very considerate towards animals and show greater kindness to them than to man. Educate the children in their infancy in such a way that they may become exceedingly kind and merciful to the animals. If an animal is sick they should endeavor to cure it; if it is hungry, they should feed it; if it is thirsty, they should satisfy its thirst; if it is tired, they should give it rest.
Man is generally sinful and the animal is innocent; unquestionably one must be more kind and merciful to the innocent. The harmful animals, such as the bloodthirsty wolf, the poisonous snake and other injurious animals are excepted, because mercy towards these is cruelty to man, and other animals. For instance, if you show kindness to a wolf this becomes a tyranny to the sheep, for it may destroy an entire flock of sheep. If you give the opportunity to a mad dog it may be the cause of the destruction of a thousand animals and men. Therefore, sympathy to the ferocious animal is cruelty to the peaceful animal, so they should be done away with. To the blessed animals, however, the utmost kindness should be exercised: the more the better it will be.
This sympathy and kindness is one of the fundamental principles of the divine kingdom. Ye should pay great attention to this question. ('Abdu'l-Baha, 'Baha'i World Faith')
