"Although you may provide food to animals you keep in cages, but you are depriving them of their freedom. Your next life may be long but you will live with limited freedom. As such, keeping animals in captivity is not worth doing, rather let them be free."

"If in this life one's hobby is netting fish and trapping birds and animals, in the next life one will be separated from one's kith and kin, from one's parents, spouse and children."
