"Life is lifes greatest gift. Guard the life of another creature as you would your own because it is your own. On lifes scale of values, the smallest is no less precious to the creature who owns it than the largest."

"In the story of the life of the Buddha, in the early days of the samgha the monks had no fixed abode but wandered throughout the year Eventually, the Buddha instructed monks to cease their peregrinations during the torrential monsoon period in order to prevent the killing of insects and worms while walking on muddy roads"

"Whenever taking a step, always watch for ants and insects. Prohibit the building of fires outside (lest insects be killed) and do not set mountain woods or forests ablaze."

"Een plaining flies to thee have spoke, Poor trifles as they be; And oft the spiders web thoust broke, To set the captive free."

"There is much debate as to whether invertebrates can feel pain, although most species show responses to adverse stimuli."

"To let go from my hand a flea that I have caught is a kinder act than to bestow a dirhem on a man in need. There is no difference between the black earless creature which I release and the Black Prince of Kinda who bound the tiara (on his head). Both of them take precaution (against death); and life is dear to it (the flea), and it passionately desires the means of living."
