All beings are not only the parents in the past. They will become the Buddha in the future. If you free their lives, you are Buddha.
Gautama BuddhaOne who does not rouse themself when it is time to rise, who, though capable, is full of sloth, whose will and thought are weak, that lazy and idle person will never find their way to true knowledge.
Gautama BuddhaJust as one can make a lot of garlands from a heap of flowers, so man, subject to birth and death as he is, should make himself a lot of good karma.
Gautama Buddha
